Subjects: subject: Algebraic Geometry (math.AG)

description: Let M be a moduli space of stable sheaves on a K3 or Abelian surface S. We express the class of the diagonal in the cartesian square of M in terms of the Chern classes of a universal sheaf. Consequently, we obtain generators of the cohomology ring of M. When S is a K3 and M is the Hilbert scheme of length n subschemes, this set of generators is sufficiently small in the sense that there aren't any relations among them in the stable cohomology ring. When S is the cotangent bundle of a Riemann surface, we recover the result of T. Hausel and M. Thaddeus: The cohomology ring of the moduli spaces of Higgs bundles is generated by the universal classes.

Asset Pricing In Multiperiod Securities Markets

Subjects: Research Methods/ Statistical Methods

description: The paper provides an intertemporal version of the capital asset pricing model (CAPM) of Sharpe and Lintner. Although we allow for general changes in the investment opportunity set and for general risk-averse preferences, there are conditions under which two mutual funds are sufficient to generate all optimal portfolios. In particular, we require that the Riesz claim, which represents the date O pricing functional for the marketed claims, should lie in a scalar Brownian information set. Then we obtain an instantaneous counterpart to the CAPM pricing formula: a linear relationship between the conditional mean returns on the securities and conditional covariances with the return on the market portfolio. Our use of option pricing techniques requires continuous trading but does not require continuous consumption. In addition, we consider a large economy with a factor structure, as in Ross' arbitrage pricing theory. The dividends are assumed to have an approximate factor structure, with the factor components lying in the information set generated by an N-dimensional Brownian motion, and with the covariance matrices of the idiosyncratic components having uniformly bounded eigenvalues. We obtain an N-factor version of the pricing formula and relate the factors to the gains processes {price change plus accumulated dividends) for well-diversified portfolios. An approximate factor structure for dividends implies an approximate factor structure for the gains processes of the securities. Furthermore, the assumption_that per.capita supply is well diversified can motivate our condition that the Riesz claim lies in an N-dimensional Brownian information set.
Current groundwater quality conditions at the historic Rum Jungle mine site, Northern Australia

description: Rum Jungle was one of Australia’s first major uranium mines and produced approximately 3,500 tonnes of uranium in the 1950s but acid rock drainage (ARD) and heavy metal mobilization at the site have led to significant environmental impacts on groundwater and the East Finniss River. Recent studies have documented a deterioration of the site’s historic reclamation works and hence a worsening scenario in terms of environmental impact. Recent data reviews identified numerous gaps in the existing network of monitoring wells at the site and hence a series of additional wells was installed in late 2010. Data from these wells have significantly improved our understanding of the extent of ARD impact at the site and hence the focus of this paper is to provide an overview of current groundwater quality conditions at the mine site.[All papers were considered for technical and language appropriateness by the organizing committee.]

description: We derive bifurcation test equations for A-series singularities of nonlinear functionals and, based on these equations, we propose a numerical method for detecting high codimensional bifurcations in parameter-dependent PDEs such as parameter-dependent semilinear Poisson equations. As an example, we consider a Bratu-type problem and show how high codimensional bifurcations such as the swallowtail bifurcation can be found numerically. In particular, our original contributions are (1) the use of the Infinite-dimensional Splitting Lemma, (2) the unified and simplified treatment of all A-series bifurcations, (3) the presentation in Banach spaces, i.e. our results apply both to the PDE and its (variational) discretization, (4) further simplifications for parameter-dependent semilinear Poisson equations (both continuous and discrete), and (5) the unified treatment of the continuous problem and its discretisation.

description: We demonstrate for the six vertex and XXZ model parameterized by $Δ=-(q+q^{-1})/2\neq \pm 1$ that when q^{2N}=1 for integer $N\geq 2$ the Bethe's ansatz equations determine only the eigenvectors which are the highest weights of the infinite dimensional sl_2 loop algebra symmetry group of the model. Therefore in this case the Bethe's ansatz equations are incomplete and further conditions need to be imposed in order to completely specify the wave function. We discuss how the evaluation parameters of the finite dimensional representations of the sl_2 loop algebra can be used to complete this specification.

description: A model for large-scale evolution recently introduced by Amaral and Meyer is studied analytically and numerically. Species are located at different trophic levels and become extinct if their prey becomes extinct. It is proved that this model is self-organized critical in the thermodynamic limit, with an exponent 2 characterizing the size distribution of extinction events. The lifetime distribution of species, cutoffs due to finite-size effects, and other quantities are evaluated. The relevance of this model to biological evolution is critically assessed.

description: We propose a new L-R symmetry model where the L-R symmetry transformation reverses both the L-R chirality and the local quantum number. We add to the model a global quantum number $F$ whose value is one for fermions (minus one for anti fermion) and vanishes for bosons. For each standard model (SM) particle, we have the corresponding L-R dual particle whose mass is very large and which should have decayed at the current low energy level. Due to the global quantum number $F$, there is no Majorana neutrino in the model but a Dirac seesaw mechanism can still occur and the usual three active neutrinos oscillation can still be realized. We add two leptoquarks and their L-R duals, for generating the baryon number asymmetry and for facilitating the decay of the L-R dual particles. The decay of the L-R dual particles will produce a large entropy to the SM sector and gives a mechanism for avoiding the big bang nucleosynthesis constraint.

Canonical Structure of Locally Homogeneous Systems on Compact Closed 3-Manifolds of Types $E^3$, Nil and Sol

description: In this paper we investigate the canonical structure of diffeomorphism invariant phase spaces for spatially locally homogeneous spacetimes with 3-dimensional compact closed spaces. After giving a general algorithm to express the diffeomorphism-invariant phase space and the canonical structure of a locally homogeneous system in terms of those of a homogeneous system on a covering space and a moduli space, we completely determine the canonical structures and the Hamiltonians of locally homogeneous pure gravity systems on orientable compact closed 3-spaces of the Thurston-type $E^3$, $\Nil$ and $\Sol$ for all possible space topologies and invariance groups. We point out that in many cases the canonical structure becomes degenerate in the moduli sectors, which implies that the locally homogeneous systems are not canonically closed in general in the full diffeomorphism-invariant phase space of generic spacetimes with compact closed spaces.

description: In the noncommutative geometry of Artin, Van den Bergh, and others, the twisted homogeneous coordinate ring is one of the basic constructions. Such a ring is defined by a $σ$-ample divisor, where $σ$ is an automorphism of a projective scheme X. Many open questions regarding $σ$-ample divisors have remained. We derive a relatively simple necessary and sufficient condition for a divisor on X to be $σ$-ample. As a consequence, we show right and left $σ$-ampleness are equivalent and any associated noncommutative homogeneous coordinate ring must be noetherian and have finite, integral GK-dimension. We also characterize which automorphisms $σ$ yield a $σ$-ample divisor.

description: This dissertation examines the use of statistical models for prediction. Examples are drawn from public policy and chosen because they represent pressing problems facing U.S. governments at the local, state, and federal level. The first five chapters provide examples where the perfunctory use of linear models, the prediction tool of choice in government, failed to produce reasonable predictions. Methodological flaws are identified, and more accurate models are proposed that draw on advances in statistics, data science, and machine learning. Chapter 1 examines skyscraper construction, where the normality assumption is violated and extreme value analysis is more appropriate. Chapters 2 and 3 examine presidential approval and voting (a leading measure of civic participation), where the non-collinearity assumption is violated and an index model is more appropriate. Chapter 4 examines changes in temperature sensitivity due to global warming, where the linearity assumption is violated and a first-hitting-time model is more appropriate. Chapter 5 examines the crime rate, where the independence assumption is violated and a block model is more appropriate. The last chapter provides an example where simple linear regression was overlooked as providing a sensible solution. Chapter 6 examines traffic fatalities, where the linear assumption provides a better predictor than the more popular non-linear probability model, logistic regression. A theoretical connection is established between the linear probability model, the influence score, and the predictivity.

Influence of the Soret effect on convection of binary fluids

description: Convection in horizontal layers of binary fluids heated from below and in particular the influence of the Soret effect on the bifurcation properties of extended stationary and traveling patterns that occur for negative Soret coupling is investigated theoretically. The fixed points corresponding to these two convection structures are determined for realistic boundary conditions with a many mode Galerkin scheme for temperature and concentration and an accurate one mode truncation of the velocity field. This solution procedure yields the stable and unstable solutions for all stationary and traveling patterns so that complete phase diagrams for the different convection types in typical binary liquid mixtures can easily be computed. Also the transition from weakly to strongly nonlinear states can be analyzed in detail. An investigation of the concentration current and of the relevance of its constituents shows the way for a simplification of the mode representation of temperature and concentration field as well as for an analytically manageable few mode description.

description: The repeated community-wide reuse of test sets in popular benchmark problems raises doubts about the credibility of reported test-error rates. Verifying whether a learned model is overfitted to a test set is challenging as independent test sets drawn from the same data distribution are usually unavailable, while other test sets may introduce a distribution shift. We propose a new hypothesis test that uses only the original test data to detect overfitting. It utilizes a new unbiased error estimate that is based on adversarial examples generated from the test data and importance weighting. Overfitting is detected if this error estimate is sufficiently different from the original test error rate. We develop a specialized variant of our test for multiclass image classification, and apply it to testing overfitting of recent models to the popular ImageNet benchmark. Our method correctly indicates overfitting of the trained model to the training set, but is not able to detect any overfitting to the test set, in line with other recent work on this topic.

Some Problems in Graph Theory and Scheduling

description: In this dissertation, we present three results related to combinatorial algorithms in graph theory and scheduling, both of which are important subjects in the area of discrete mathematics and theoretical computer science. In graph theory, a graph is a set of vertices and edges, where each edge is a pair of vertices. A coloring of a graph is a function that assigns each vertex a color such that no two adjacent vertices share the same color. The first two results are related to coloring graphs belonging to specific classes. In scheduling problems, we are interested in how to efficiently schedule a set of jobs on machines. The last result is related to a scheduling problem in an environment where there is uncertainty on the number of machines.
      The first result of this thesis is a polynomial time algorithm that determines if an input graph containing no induced seven-vertex path is 3-colorable. This affirmatively answers a question posed by Randerath, Schiermeyer and Tewes in 2002. Our algorithm also solves the list-coloring version of the 3-coloring problem, where every vertex is assigned a list of colors that is a subset of {1, 2, 3}, and gives an explicit coloring if one exists. This is joint work with Flavia Bonomo, Maria Chundnovsky, Peter Maceli, Oliver Schaudt, and Maya Stein.
      A graph is H-free if it has no induced subgraph isomorphic to H. In the second part of this thesis, we characterize all graphs $H$ for which there are only finitely many minimal non-three-colorable H-free graphs. This solves a problem posed by Golovach et al. We also characterize all graphs H for which there are only finitely many H-free minimal obstructions for list 3-colorability. This is joint work with Maria Chudnovsky, Jan Goedgebeur and Oliver Schaudt.
      The last result of this thesis deals with a scheduling problem addressing the uncertainty regarding the machines. We study a scheduling environment in which jobs first need to be grouped into some sets before the number of machines is known, and then the sets need to be scheduled on machines without being separated. In order to evaluate algorithms in such an environment, we introduce the idea of an alpha-robust algorithm, one which is guaranteed to return a schedule on any number m of machines that is within an alpha factor of the optimal schedule on m machines, where the optimum is not subject to the restriction that the sets cannot be separated. Under such environment, we give a (5/3+epsilon)-robust algorithm for scheduling on parallel machines to minimize makespan, and show a lower bound of 4/3.  For the special case when the jobs are infinitesimal, we give a 1.233-robust algorithm with an asymptotic lower bound of 1.207. This is joint work with Clifford Stein.

description: The observation that the 2+1 dimensional BTZ black hole can be obtained as a quotient space of anti-de Sitter space leads one to ask what causal behaviour other such quotient spaces can display. In this paper we answer this question in 2+1 and 3+1 dimensions when the identification group has one generator. Among other things we find that there does not exist any 3+1 generalization of the rotating BTZ hole. However, the non-rotating generalization exists and exhibits some unexpected properties. For example, it turns out to be non-static and to possess a non-trivial apparent horizon.

description: Introduction Congenital disorders of glycosylation (CDG) are among the inherited metabolic diseases caused by a defect in protein glycosylation. We have used our modified FASP protocol (‘glycoFASP’) to determine the structures of normal and CDG Type 1 patient Nglycans. Objective Develop a simple FANGS3 protocol to isolate and analyze glycoprotein glycans from human serum. • Apply the glycoFASP method to compare N-glycan profiles between normal control and CDG Type 1 patient. Methodology [Refer to Poster]. Results glycoFASP-released glycans from normal control and CDG Type 1 patient were analysed using MALDI –TOF/TOF MS are shown in Figure 1. The spectrum shows glycans signal (m/z 1419, 1581 and 1744 ) are not observed from CDG Type 1 patient when compared to normal control spectrum. Normal control also produce non fucosylated (m/z 1501) and fucosylated (m/z 1485,1648 and 1810) complex biantennary, bisecting GlcNAc (m/z 1689, 1851, 2013 and 2175) and sialylated (m/z 1955, 2101 and 2246) glycans. Interestingly, CDG Type 1 spectrum also show non fucosylated (m/z 1501) and fucosylated (m/z 1485,1648 and 1810) complex bi-antennary, sialylated (m/z 1955,2101 and 2246) and bisecting GlcNAc (m/z 1689, 1851 and 2013) glycans lacking (m/z 2175 ). These N-glycans signal are markedly lower compared to normal control. Conclusion The difference between normal control and CDG Type 1 glycan structures has been demonstrated. • The protocol is less laborious and reduces time in sample preparation before MALDI analysis. • The protocol works efficiently and convenience for low volume of sample.

description: This thesis examines orbifold versions of three results concerning the existence of canonical metrics in the Kahler setting. The first of these is Yau's solution to Calabi's conjecture, which demonstrates the existence of a Kahler metric with prescribed Ricci form on a compact Kahler manifold. The second is a variant of Yau's solution in a certain non-compact setting, namely, the setting in which the Kahler manifold is assumed to be asymptotic to a cone. The final result is one due to Uhlenbeck and Yau which asserts the existence of Kahler-Einstein metrics on stable vector bundles over compact Kahler manifolds.
title: Stability of Low Crested and Submerged Breakwaters: A Reanalysis and Model Development
Creators: name: Burgess, Christopher P.
Publisher: name: Old Dominion University Libraries
Year: 2021

description: Low-crested and submerged structures (LCS) play an integral part in the stabilization of shorelines for recreational purposes, yet there are a plethora of empirical models and gaps in the understanding of their stability and damage progression. The objectives were: i) to evaluate the present formulae, ii) explore variable importance, iii) formulate a stability model, iv) extend the current datasets and v) explore a new model for LCS. The literature points to an increasing understanding of the initiation of damage of LCS and recent exploration of the shear stress-induced erosion (van Rijn, 2019). Assessment of two existing models (Kramer, 2006 and Van der Meer and Daemen, 1994) points to reliability in predicting initiation of damage but limitations in skill in modelling progression of damage, for Re >40,000. Two analytical models (and two variations) developed herein point to difficulty (skill) in predicting damage initiation (progression) and the benefit of removing transmitted wave energy. A scale model testing programme added 124 new data points and confirms the importance of relative crest height, increased relative vulnerability of the seaward slope and crest and damage progression. Exploration of several improvements in the model was useful in deriving an LCS model that predicted damage similar to the pooled data and offered insights into the importance of i) seaward slope erosion, ii) drag and lift forces, and iii) Shield's stress relation to relative depth and stone size, Re and gradation. Importantly, damage progression is likely to be non-linear. The model is likely to be conservative and best applied for S<10. A comparative assessment to Van der Meer and Daemen model suggests that it predicts marginally lower (higher) damage for limited (extended) number of waves (in damage progression). A simplified "Rule of Thumb" suggest a relationship similar to Burcharth et al., 2006 and Pilarczyk, 2003 models.

description: Introduction Mucopolysaccharidoses Type II is caused by an X-linked mutation in IDS gene which produce an enzyme called iduronate 2-sulfatase (IDS) that is essential for the breakdown of glycosaminoglycans. Lack of IDS enzyme activity leads to the accumulation of heparan sulfate and dermatan sulfate within the lysosomes. Apart from enzyme replacement therapy, current treatments of MPS II have been a challenge especially in finding donor for bone marrow transplantation. Thus, this study aims to evaluate the various heparin oligosaccharides (HO) on IDS activities as potential pharmacological chaperone (PC). Materials & Methods HO (H004, H008, H010, H012, H014, H016, H018 and H020) in several concentrations were used in this study. Enzyme inhibition assay is as illustrated in Figure 1. All HO candidates were also tested on ATCC cell for specificity testing. Results The results of this study is summarized in Table 1. Three selected inhibition profiling of potential small molecules are depicted in Figure 2. No significant difference (p>0.05) was observed in the inhibition of IDS activity in ATCC cells which proves its specificity on IDS. Discussion and Conclusion PCs are small molecules that have an affinity to mutant enzymes and directly bind to them which improve their folding, stability, and enzymatic activity. Ideal PC of potent inhibitor exhibits low concentration of 50% inhibition of enzyme activity (IC50) with high inhibition constant (Ki) of the dissociation between the enzyme-inhibitor complex or the reciprocal of the binding affinity of the inhibitor to the enzyme. Out of eight species of HO tested, three demonstrate as PC with Ki and IC50 (µM) of 59.27 & 19.40; 34.40 & 95.51; and 11.55 & 7.19 for H004, H008 and H018, respectively. As conclusion, three potential small molecules (H004, H008 and H018) with high Ki with low IC50 have been identified as potential pharmacological chaperone. Future research will be done on thermal stability analysis and cell-based experiments.

Psychopathology

description: Tim Bayne and Elisabeth Pacherie (2007) propose an integrated model for agentive awareness that incorporates features from both the narrator and the comparator-based accounts found in the literature. Although they think the comparator system is responsible for generating the bulk of agentive experience, they believe the narrator module is responsible for forming agentive judgments and conceptually-laden intentions. Crucially, they also suggest that in some instances the narrator module may “override” the deliverances of the low-level comparator mechanisms. In this paper, I apply Bayne and Pacherie’s integrated model to account for an issue in the psychopathology literature, namely the presence of anosognosia (i.e. ignorance with respect to one’s illness) in anorexia nervosa. In particular, I show that by implementing the integrated model we can solve a problem that arises out of a recent advancement in the empirical literature concerning anorexia’s pathogenesis and persistence. If my proposal is correct, the explanatory power of implementing an integrated model for agentive awareness would bolster Bayne and Pacherie’s account. It may also be of use to researchers seeking to develop a better understanding of anosognosia in anorexia nervosa, which remains a poorly understood feature of the disorder

description: This dissertation is a study of popular music and state-controlled radio broadcasting in the Arabic-speaking world, focusing on Syria and the Syrian radioscape, and a set of American stations named Radio Sawa. I examine American and Syrian politically directed broadcasts as multi-faceted objects around which broadcasters and listeners often differ not only in goals, operating assumptions, and political beliefs, but also in how they fundamentally conceptualize the practice of listening to the radio. Beginning with the history of international broadcasting in the Middle East, I analyze the institutional theories under which music is employed as a tool of American and Syrian policy, the imagined youths to whom the musical messages are addressed, and the actual sonic content tasked with political persuasion. At the reception side of the broadcaster-listener interaction, this dissertation addresses the auditory practices, histories of radio, and theories of music through which listeners in the sonic environment of Damascus, Syria create locally relevant meaning out of music and radio. Drawing on theories of listening and communication developed in historical musicology and ethnomusicology, science and technology studies, and recent transnational ethnographic and media studies, as well as on theories of listening developed in the Arabic public discourse about popular music, my dissertation outlines the intersection of the hypothetical listeners defined by the US and Syrian governments in their efforts to use music for political ends, and the actual people who turn on the radio to hear the music.

description: Introduction Mucopolysaccharidoses Type II (MPS II) is a rare inherited disease caused by mutation in IDS gene encoding iduronate-2-sulphatase (IDS), an important enzyme in the glycosaminoglycans degradation pathway of heparan sulphate and dermatan sulphate. Current treatments such as enzyme replacement therapy is not effective in reducing the central nervous system manifestation while finding the suitable donor quite challenging in bone marrow transplantation. The use of small molecules in assisting misfolding protein has been explored as an alternative approach for potential therapy in MPS II treatment. In this study, we performed the inhibition assay of desulphated heparin oligosaccharides (DSH) small molecules using recombinant human iduronate-2-sulphatase (rhIDS) to identify potential candidate as pharmacological chaperone for MPS II. Material and Methods The small molecules of DSH (DSH004, DSH006, DSH008, DSH010 & DSH012) were used in this study. All of the DSH candidates were tested in the inhibition assay as described in product insert of recombinant human iduronate 2-sulphatase (rhIDS) (2) (Figure 1). All DSH candidates were also tested on ATCC cell for specificity testing. Results The results of inhibition assay for DSH candidates were shown in table 1. ▪ Figure 2 illustrated the inhibition profiling of each small molecules of DSH. There were no significant different in the inhibition of IDS activity in ATCC cells (p>0.05). Discussion and Conclusion Inhibition concentration (IC50) referring to concentration required to produce 50% inhibition of enzyme activity. A lower IC50 generally means a more potent inhibitor (3) while inhibition constant (Ki ) indicates the binding affinity of the inhibitors. It was observed that DSH004 shows the highest value of IC50 and Ki compared to other DSH candidates. Although DSH004 demonstrate the highest Ki value, high IC50 value may cause toxicity to the cells. Overall, among all DSH candidates, DSH006 shows a promising outcome in inhibiting the IDS activity and therefore may have the potential to be a suitable candidate as the pharmacological chaperone for MPS II.
Integrated hydrogeological and environmental restoration of landslides affecting a large asbestos mine dry tailings dump

description: The Balangero asbestos open pit mine, located 35km NW of Torino (Italy), was the largest operation of this kind in Western Europe. The dry tailings were lifted by a conveyor belt from the mill and dumped over a natural slope with an approximate angle of 25 degrees, progressively reaching a maximum thickness estimated at 80 m. Mining operations ended at the beginning of the ‘70s. By the '80s the dump was deeply scarred by various local and large scale instabilities, to the point that houses located at the toe, on the opposite side of the valley, were evacuated. The award winning restoration project used a multidisciplinary approach including hydraulics, geotechnical, pedological and risk engineering to yield a well balanced and sustainable solution. This paper illustrates the Risk Based Decision Making (RBDM) process used through the feasibility, design and construction follow-up of the environmental restoration of the 60 Mm3 dry Balangero asbestos tailings dump.

description: Given a closed symplectic manifold $(M,ω)$ we introduce a certain quantity associated to a tuple of conjugacy classes in the universal cover of the group ${\hbox{\it Ham}} (M,ω)$ by means of the Hofer metric on ${\hbox{\it Ham}} (M,ω)$. We use pseudo-holomorphic curves involved in the definition of the multiplicative structure on the Floer cohomology of a symplectic manifold $(M,ω)$ to estimate this quantity in terms of actions of some periodic orbits of related Hamiltonian flows. As a corollary we get a new way to obtain Agnihotri-Belkale-Woodward inequalities for eigenvalues of products of unitary matrices. As another corollary we get a new proof of the geodesic property (with respect to the Hofer metric) of Hamiltonian flows generated by certain autonomous Hamiltonians. Our main technical tool is K-area defined for Hamiltonian fibrations over a surface with boundary in the spirit of L.Polterovich's work on Hamiltonian fibrations over $S^2$.

description: Recently, deep generative models have become increasingly popular in unsupervised anomaly detection. However, deep generative models aim at recovering the data distribution rather than detecting anomalies. Besides, deep generative models have the risk of overfitting training samples, which has disastrous effects on anomaly detection performance. To solve the above two problems, we propose a Self-adversarial Variational Autoencoder with a Gaussian anomaly prior assumption. We assume that both the anomalous and the normal prior distribution are Gaussian and have overlaps in the latent space. Therefore, a Gaussian transformer net T is trained to synthesize anomalous but near-normal latent variables. Keeping the original training objective of Variational Autoencoder, besides, the generator G tries to distinguish between the normal latent variables and the anomalous ones synthesized by T, and the encoder E is trained to discriminate whether the output of G is real. These new objectives we added not only give both G and E the ability to discriminate but also introduce additional regularization to prevent overfitting. Compared with the SOTA baselines, the proposed model achieves significant improvements in extensive experiments. Datasets and our model are available at a Github repository.

description: We analyze Optimal Velocity Model (OVM) with explicit delay. The properties of congestion and the delay time of car motion are investigated by analytical and numerical methods. It is shown that the small explicit delay time has almost no effects. In the case of the large explicit delay time, a new phase of congestion pattern of OVM seems to appear.

description: We prove two lemmata about Schubert calculus on generalized flag manifolds G/B, and in the case of the ordinary flag manifold GL_n/B we interpret them combinatorially in terms of descents, and geometrically in terms of missing subspaces. One of them gives a symmetry of Schubert calculus that we christen_descent-cycling_. Computer experiment shows that these lemmata suffice to determine all of GL_n Schubert calculus through n=5, and 99.97%+ at n=6. We use them to give a quick proof of Monk's rule. The lemmata also hold in equivariant (``double'') Schubert calculus for Kac-Moody groups G.
