Linear transformations of symmetric tensor spaces which preserve rank 1
Creators: name: Cummings, Larry
Publisher: name: University of British Columbia
Year: 2011

description: If r > 1 is an integer then U(r) denotes the vector space of r-fold symmetric tensors and Pr[U] is the set of rank 1 tensors in U(r). Let U be a finite-dimensional vector space over an algebraically closed field of characteristic not a prime p if r = p[formula omitted] for some positive integer k. We first determine the maximal subspaces of rank 1 symmetric tensors. Suppose h is a linear mapping of U(r) such that h(Pr[U]) ⊆ Pr[U] and ker h ⋂ Pr[U] = 0. We have shown that every such h is induced by a non-singular linear mapping of U, provided dim U > r+1 . This work partially answers a question raised by Marcus and Newman (Ann. of Math., 75, (1962) p.62.).

description: Recognition of iris based on Visible Light (VL) imaging is a difficult problem because of the light reflection from the cornea. Nonetheless, pigment melanin provides a rich feature source in VL, unavailable in Near-Infrared (NIR) imaging. This is due to biological spectroscopy of eumelanin, a chemical not stimulated in NIR. In this case, a plausible solution to observe such patterns may be provided by an adaptive procedure using a variational technique on the image histogram. To describe the patterns, a shape analysis method is used to derive feature-code for each subject. An important question is how much the melanin patterns, extracted from VL, are independent of iris texture in NIR. With this question in mind, the present investigation proposes fusion of features extracted from NIR and VL to boost the recognition performance. We have collected our own database (UTIRIS) consisting of both NIR and VL images of 158 eyes of 79 individuals. This investigation demonstrates that the proposed algorithm is highly sensitive to the patterns of cromophores and improves the iris recognition rate.

description: Context: With the increasing knowledge of the terrestrial planets due to recent space probes it is possible to model their rotation with increasing accuracy. Despite that fact, an accurate determination of Venus precession and nutation is lacking. Aims : Although Venus rotation has been studied in several aspects, a full and precise analytical model of its precession-nutation motion remains to be constructed. We propose to determine this motion with up-to-date physical parameters of the planet Methods: We adopt a theoritical framework already used for a precise precession-nutation model of the Earth, based on a Hamiltonian formulation, canonical equations and an accurate development of the perturbing function due to the Sun. Results: After integrating the disturbing function and applying the canonical equations, we can evaluate the precession constant $\dotΨ$ and the coefficients of nutation, both in longitude and in obliquity. We get $\dotΨ=4474".35/Jcy \pm 66.5 $, corresponding to a precession period of $28965.10 \pm 437$ years. This result, based on recent estimations of the Venus moment of inertia is significantly different from previous estimations. The largest nutation coefficient in longitude with an argument $2L_{S}$ (where $L_{S}$ is the longitude of the Sun) has a 2"19 amplitude and a 112.35 d period. We show that the coefficients of nutation of Venus due to its triaxiality are of the same order of amplitude as these values due to its dynamical flattening, unlike of the Earth, for which they are negligible.

description: Nowadays, information technology has been deeply integrated in our daily life. However, within its rapid development, it faces a serious bottleneck due to the prohibitive power consumption and limited transmission bandwidth of electrical interconnects. Silicon photonics introduces a potential solution for information technology based on optical communication. In this field, delay-bandwidth devices offer a high bandwidth optical interconnection and low power consumption for the next generation information communication technology. Through introducing the slow light effect, I can realise time domain control and store the light to achieve a new functional component, which is the optical buffer for optical information processing. The optical buffer allows us to control and store the light, using as the optical information process and transit. However, the current optical buffer devices are limited by high optical loss and the ability to produced tunable group delay of the light. In this thesis, I examine different configurations of the coupled photonic crystal resonator system and then introduce a novel tuneable delay line, based on photonic crystal cavity structures. Through the optical analog to electromagnetically induced transparency (EIT), an EIT-like transmission spectrum has been achieved in coupled photonic crystal cavities. By tuning the phase difference between two coupled resonators and resonance wavelength, I can achieve the desired analog conditions and reach to a maximum group delay of 360 ps. By adding thermal tuning pattern, I have demonstrated a tuning of the group delay of over 120 ps range at a low input power and a maximum delay of 300 ps group delay in coupled photonic crystal cavities system. All devices are with a footprint at only 200 μm², and with integrated compatibles as well. By employing a new vertical coupling technique, a record low loss 15 dB/ns is presented making this system very promising for practical optical information applications.

description: We review methods developed in the gauge-string duality to treat energy loss by energetic probes of a strongly coupled thermal medium. After introducing the black hole description of the thermal medium, we discuss the trailing string behind a heavy quark and the drag force that it implies. We then explain how to solve the linearized Einstein equations in the presence of the trailing string and extract from the solutions the energy density and the Poynting vector of the dual gauge theory. We summarize some efforts to compare these calculations to heavy ion phenomenology.

description: Cold neutrons are converted to ultra-cold neutrons (UCN) by the excitation of a single phonon or multiphonons in superfluid helium. The dynamic scattering function S(q, omega) of the superfluid helium strongly depends on pressure, leading to a pressure- dependent differential UCN production rate. A phenomenological expression for the multiphonon part of the scattering function s(lambda) describing UCN production has been derived from inelastic neutron scattering data. When combined with the production rate from single phonon processes this allows us to calculate the UCN production for any incident neutron flux. For calculations of the UCN production from single phonon processes we propose to use the values for S*(SVP) = 0.118(8) and S*(20 bar) = 0.066(6). As an example we will calculate the expected UCN production rate at the cold neutron beam for fundamental physics PF1b at the Institut Laue Langevin. We conclude that UCN production in superfluid helium under pressure is not attractive.

description: Property A was introduced by Yu as a non-equivariant analogue of amenability. Nigel Higson posed the question of whether there is a homological characterisation of property A. In this paper we answer Higson's question affirmatively by constructing analogues of group cohomology and bounded cohomology for a metric space X, and show that property A is equivalent to vanishing cohomology. Using these cohomology theories we also give a characterisation of property A in terms of the existence of an asymptotically invariant mean on the space.
Mandatory Intubation of Patients Undergoing Thrombectomy: Clinical De -  cision Model for Reducing COVID-19 Exposure

description: Background and Purpose— Our aim was to determine the value of mandatory intubation in patients requiringthrombectomy as a means for reducing in-hospital exposure for undiagnosed corona virus disease 2019 (COVID-19)among acute ischemic stroke patients, and the factors that influence this decision.Methods— We constructed two probabilistic decision trees, one addressing the potential benefit to the patient, andthe second addressing the potential benefit to the medical professionals involved in direct patient care. We based themodel on the role of endotracheal intubation within the scope of using thrombectomy for acute stroke treatment, andits impact on the exposure of medical professionals.Results— The utility of mandated intubation for acute ischemic stroke patients prior to mechanical thrombectomyis inferior to that of undergoing such procedure only if clinically indicated (5.53 vs. 6.00 QALYs). Only two of theinput variables (i.e. the case fatality rate and disability from acute ischemic stroke) were found to have thresholdvalues within their plausible ranges, although very close to their highest values. Both extreme analyses also demon-strated the superiority of avoiding mandatory endotracheal intubation in patients, irrespective of setting the valuesof the input variable with a bias to benefit compulsory intubation (5.81 vs. 5.74 QALY), or with a bias disfavoring it(5.90 vs. 4.15 QALY).Conclusions— Our analysis does not support mandatory intubation in every acute ischemic patient prior to me-chanical thombectomy. Based on our assumptions, intubation based on clinical need as used prior to COVID-19pandemic appears to be the superior approach.

description: The purpose of this work is to fabricate ribbon-like InGaAs and InAsP wires embedded in InP ridge structures and investigate their transport properties. The InP ridge structures that contain the wires are selectively grown by chemical beam epitaxy (CBE) on pre-patterned InP substrates. To optimize the growth and micro-fabrication processes for electronic transport, we explore the Ohmic contact resistance, the electron density, and the mobility as a function of the wire width using standard transport and Shubnikov-de Haas measurements. At low temperatures the ridge structures reveal reproducible mesoscopic conductance fluctuations. We also fabricate ridge structures with submicron gate electrodes that exhibit non-leaky gating and good pinch-off characteristics acceptable for device operation. Using such wrap gate electrodes, we demonstrate that the wires can be split to form quantum dots evidenced by Coulomb blockade oscillations in transport measurements.

description: Diclofenac is an NSAID, Non-Steroidal Anti-Inflammatory Drugs, widely used clinically in the treatement of osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis, and has been available in the United States since 1988 (Banks et al. 1995). Diclofenac can cause hepatotoxicity, and despite the rare nature of these events, affects a large number of people due to its widespread usage. It is one of the most common drugs associated with idiosyncratic hepatic injury (Daly et al. 2007). From November 1988 to June 1991 the FDA received 180 cases of diclofenac-induced adverse hepatic injury of which 79\% were female, 71\% were elderly patients (above the age of 60), and 77\% of the patients had osteoarthritis. In most of the cases the liver injury was characterized by hepatocellular damage or mixed hepatocellular injury, and there were some cases of cholestasis (Banks et al. 1995). The incidence of diclofenac hepatotoxicity has been reported to be 6.3 per 100 000 patients (DeAbajo et al. 2004). Bioactivation to reactive intermediates, their disposition, the production of oxidative stress, mitochondrial damage, and immune-mediated mechanisms have been suggested to play a role in diclofenac-mediated liver toxicity

An inequality in generalized sobolev spaces
Creators: name: Kanigan, Lawrence Louis
Publisher: name: University of British Columbia
Year: 2011

description: In the study of the spaces (formula omitted) of functions for which the pth powers of all the derivatives up to order ℓ are summable in the domain Ω⊂R, it has been found that there are mutual relations between various spaces. These relations were developed under the name "embedding theorems". The first embedding theorem (for spaces (formula omitted) were proved by Sobolev [3]*. Subsequently these spaces became known as Sobolev Spaces. However, in the study of existence of solutions for well-posed boundary value problems, there arose the necessity to consider spaces of distributions: an example is the space dual to (formula omitted). For a thorough development of distributions see L. Schwarz's texts [4]. Furthermore, the classes of Sobolev spaces had to be widened to fractional values of ℓ, the latter spaces being particularly useful in the study of non-linear problems. This thesis follows the development of generalized Sobolev spaces as in Volevich and Panayakh [1]. In section I we prove the basic theorems in this formulation. In section II, the existence of a function is proved using the formulation of section II. The proof of the proposition in which a modification has been made was given by Agranovich and Vishik [2]. The proposition is essential to the applications of Sobolev spaces to differential operators. The result states that ll u ll µ ≤ constant ll u,Ω ll µ for (formula omitted) for the particular case when the weighting function is (formula omitted) and Ω is a half-line. (For definitions see section I). Section III is devoted to a brief comparison of this formulation of Sobolev spaces to other approaches.

On multidegree of tame and wild automorphisms of C^3

description: In this note we show that the set mdeg(Aut(C^3)) mdeg(Tame(C^3)) is not empty. Moreover we show that this set has infinitely many elements. Since for the famous Nagata's example N of wild automorphism, mdeg N =(5,3,1) is an element of mdeg(Tame(C^3)) and since for other known examples of wild automorphisms the multidegree is of the form (1,d_2,d_3) (after permutation if neccesary), then we give the very first exmple of wild automorphism F of C^3 such that mdeg F does not belong to mdeg(Tame(C^3)). We also show that, if d_1,d_2 are odd numbers such that gcd (d_1,d_2) =1, then (d_1,d_2,d_3) belongs to mdeg(Tame(C^3)) if and only if d_3 is a linear combination of d_1,d_2 with natural coefficients. This a crucial fact that we use in the proof of the main result.
Controlled generation of field squeezing with cold atomic clouds coupled to a superconducting transmission line resonator

description: We propose an efficient method for controlled generation of field squeezing with cold atomic clouds trapped close to a superconducting transmission line resonator. It is shown that, based on the coherent strong magnetic coupling between the collective atomic spins and microwave fields in the transmission line resonator, two-mode or single mode field squeezed states can be generated through coherent control on the dynamics of the system. The degree of squeezing and preparing time can be directly controlled through tuning the external classical fields. This protocol may offer a promising platform for implementing scalable on-chip quantum information processing with continuous variables.

description: In the context of this work, we have developed intelligent controllers, based on Fuzzy Logic and Neural Networks, that allow a differential drive robotic vehicle, to navigate in a pre-constructed simulated environment. The vehicle moves and follows a pre-determined trajectory by simultaneously avoiding unknown obstacles. To evaluate the proposed approach, we have developed simulated scenarios with incremental difficulty. Based on these scenarios, we have performed an analysis, to study how the structure of the individual controllers affects the overall performance. Extensive simulated results are presented to
compare and highlight the efficiency of the individual controllers.

description: A theoretical model is presented which explains the dominant decoherence process in a microcavity polariton condensate. The mechanism which is invoked is the effect of self-phase modulation, whereby interactions transform polariton number fluctuations into random energy variations. The model shows that the phase coherence decay, g1(t), has a Kubo form, which can be Gaussian or exponential, depending on whether the number fluctuations are slow or fast. This fluctuation rate also determines the decay time of the intensity correlation function, g2(t), so it can be directly determined experimentally. The model explains recent experimental measurements of a relatively fast Gaussian decay for g1(t), but also predicts a regime, further above threshold, where the decay is much slower.

description: Rhabdomyosarcoma (RMS) is the most common soft tissue sarcoma in children and accounts for about 5% of all malignant paediatric tumours. β-Catenin, a multifunctional nuclear transcription factor in the canonical Wnt signaling pathway, is active in myogenesis and embryonal somite patterning. Dysregulation of Wnt signaling facilitates tumour invasion and metastasis. This study characterizes Wnt/β-catenin signaling and functional activity in paediatric embryonal and alveolar RMS. Immunohistochemical assessment of paraffin-embedded tissues from 44 RMS showed β-catenin expression in 26 cases with cytoplasmic/membranous expression in 9/14 cases of alveolar RMS, and 15/30 cases of embryonal RMS, whereas nuclear expression was only seen in 2 cases of embryonal RMS. The potential functional significance of β-catenin expression was tested in four RMS cell lines, two derived from embryonal (RD and RD18) RMS and two from alveolar (Rh4 and Rh30) RMS. Western blot analysis demonstrated the expression of Wnt-associated proteins including β-catenin, glycogen synthase kinase-3β, disheveled, axin-1, naked, LRP-6 and cadherins in all cell lines. Cell fractionation and immunofluorescence studies of the cell lines (after stimulation by human recombinant Wnt3a) showed reduced phosphorylation of β-catenin, stabilisation of the active cytosolic form and nuclear translocation of β-catenin. Reporter gene assay demonstrated a T-cell factor/lymphoid-enhancing factor-mediated transactivation in these cells. In response to human recombinant Wnt3a, the alveolar RMS cells showed a significant decrease in proliferation rate and induction of myogenic differentiation (myogenin, MyoD1 and myf5). These data indicate that the central regulatory components of canonical Wnt/β-catenin signaling are expressed and that this pathway is functionally active in a significant subset of RMS tumours and might represent a novel therapeutic target.

description: The eigenvalue problem of the spherically symmetric oscillator Hamiltonian is revisited in the context of canonical raising and lowering operators. The Hamiltonian is then factorized in terms of two not mutually adjoint factorizing operators which, in turn, give rise to a non-Hermitian radial Hamiltonian. The set of eigenvalues of this new Hamiltonian is exactly the same as the energy spectrum of the radial oscillator and the new square-integrable eigenfunctions are complex Darboux-deformations of the associated Laguerre polynomials.

title: Point processes and integer-valued time series
Creators: name: Chen, Zezhun
Publisher: name: London School of Economics and Political Science (LSE)
Year: 2023

description: This thesis explores two primary themes across five scientific papers: Integer-value time series and their relationship with classical point processes. The first part of the thesis focuses on the development and application of Integer-valued autoregressive (INAR) models, extending from univariate to multivariate cases, with applications in financial and insurance count data. In Paper A, we introduce a new family of binomial-mixed Poisson INAR model of order one, INAR(1), by incorporating a mixed Poisson component to the innovation of the classical Poisson INAR(1). This allows for the capture of overdispersion and serial correlation evident in financial count data. Furthermore, we explore its distributional properties, estimation procedure and asymptotic properties and apply the model to iceberg count data from financial system. In Paper B, we extending beyond univariate case, introducing a novel family of multivariate mixed Poisson-Generalized Inverse Gaussian INAR(1), MMPGIG-INAR(1), regression models for modelling multivariate count time series. This family of models can accommodate a wide range of dispersion and cross-sectional correlation structures due to the flexibility in the parameter setting of the Generalized Inverse Gaussian. We then illustrate different members of the MMPGIG-INAR(1) through applying the model to Local Government Property Insurance Fund data from the state of Wisconsin. In Paper C, we develop novel Expectation-Maximization estimation algorithm for maximum likelihood estimation of bivariate mixed Poisson INAR(1) model. This method is readily extensible to the multivariate case. We examine three different mixing densities, univariate gamma, bivariate Lognormal and bivariate copula and demonstrate the algorithm through fitting the same used in Paper B. The second part of the thesis shifts focus to integer-valued approximation of classical point processes and applications of point process on Covid data modelling. In Paper D, we represent the Cox process and the dynamic contagion process, which is a Hawkes process whose immigration part is a Cox process, as limit of timeseries based point processes, namely integer-valued moving average model (INMA) and Integer-valued Autoregressive Moving Average model (INARMA). This would potentially facilitate the statistical inference of classical point processes. In Paper E, we propose a new type of univariate and bivariate Integer-valued autoregressive model of order one, INAR(1), to approximate univariate and bivariate linear birth and death process with constant rates. Due to the simplicity of Markov structure of INAR model, we demonstrate through simulation study that the parameters of linear birth and death process can be estimated through Quasi-likelihood function of INAR model.

description: A modified formulation of the Electroweak Model with 3-dimensional spherical geometry in the target space is suggested. The {\it free} Lagrangian in the spherical field space along with the standard gauge field Lagrangian form the full Higgsless Lagrangian of the model, whose second order terms reproduce the same experimentally verified fields with the same masses as the Standard Electroweak Model. The vector bosons masses are automatically generated, so there is no need in special mechanism of spontaneous symmetry breaking. The limiting case of the modified Higgsless Electroweak Model, which corresponds to the contracted gauge group $SU(2;j)\times U(1)$ is discussed. Within framework of the limit model Z-boson, electromagnetic and electron fields are interpreted as an external ones with respect to W-bosons and neutrino fields. The W-bosons and neutrino fields do not effect on these external fields. The masses of all particles remain the same, but the field interactions in contracted model are more simple as compared with the standard Electroweak Model due to nullification of some terms.

description: Recently a modification of the tachyon DBI action has been proposed in which the tachyon carries the internal CP matrix σ_1 and σ_2. In this paper, we find the momentum expansion of the disk level S-matrix element of four tachyons and one gauge field in superstring theory and show that the first and second order terms of the expansion are in perfect agreement with the above tachyon DBI action.

description: We present ISAAC spectroscopy and ISAAC, UKIDSS and Spitzer Space Telescope broad-band photometry of SDSS J1228+1040 -- a white dwarf for which evidence of a gaseous metal-rich circumstellar disk has previously been found from optical emission lines. The data show a clear excess in the near- and mid-infrared, providing compelling evidence for the presence of dust in addition to the previously identified gaseous debris disk around the star. The infrared excess can be modelled in terms of an optically thick but geometrically thin disk. We find that the inner disk temperatures must be relatively high (~1700 K) in order to fit the SED in the near-infrared. These data provide the first evidence for the co-existence of both gas and dust in a disk around a white dwarf, and show that their presence is possible even around moderately hot (~22,000 K) stars.

Numerical solution of boundary value problems in ordinary differential equations
Creators: name: Usmani, Riaz Ahmad
Publisher: name: University of British Columbia
Year: 2011

description: In the numerical solution of the two point "boundary value problem, [ equation omitted ] (1) the usual method is to approximate the problem by a finite difference analogue of the form [ equation omitted ] (2) with k = 2, and the truncation error T.E. = O(h⁴) or O(h⁶), where h is the step-size. Varga (1962) has obtained error bounds for the former when the problem (1) is linear and of class M . In this thesis, more accurate finite difference methods are considered. These can be obtained in essentially two different ways, either by increasing the value k in difference equations (2), or by introducing higher order derivatives. Several methods of both types have been derived. Also, it is shown how the initial value problem y' = ϕ(x,y) can be formulated as a two point boundary value problem and solved using the latter approach. Error bounds have been derived for all of these methods for linear problems of class M . In particular, more accurate bounds have been derived than those obtained by Varga (1962) and Aziz and Hubbard (1964). Some error estimates are suggested for the case where [ equation omitted ], but these are not accurate bounds, especially when [ equation omitted ] not a constant. In the case of non-linear differential equations, sufficient conditions are derived for the convergence of the solution of the system of equations (2) by a generalized Newton's method. Some numerical results are included and the observed errors compared with theoretical error bounds.

description: We present the detailed bifurcation structure and associated flow patterns near the onset of zero Prandtl number Rayleigh Bénard convection. We employ both direct numerical simulation and a low-dimensional model ensuring qualitative agreement between the two. Various flow patterns originate from a stationary square observed at a higher Rayleigh number through a series of bifurcations starting from a pitchfork followed by a Hopf and finally a homoclinic bifurcation as the Rayleigh number is reduced to the critical value. Global chaos, intermittency, and crises are observed near the onset.

description: We present a precise measurement of the ratio R_K = Γ(Ke2(γ))/Γ(K\mu2(γ)) performed with the KLOE detector. The results are based on data collected at the Frascati e^+e^- collider DAFNE for an integrated luminosity of 2.2 fb^{-1}. We find R_K = (2.493\pm0.025_{stat}\pm0.019_{syst})\times 10^{-5}, in agreement with the Standard Model expectation. This result is used to improve constraints on parameters of the Minimal Supersymmetric Standard Model with lepton flavor violation.

Superconductivity on the density wave background with soliton-wall structure

Publisher: name: arXiv
Year: 2008
Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: Superconductivity (SC) may microscopically coexist with density wave (DW) when the nesting of the Fermi surface (FS) is not perfect. There are, at least, two possible microscopic structures of a DW state with quasi-particle states remaining on the Fermi level and leading to the Cooper instability: (i) the soliton-wall phase and (ii) the small ungapped Fermi-surface pockets. The dispersion of such quasi-particle states strongly differs from that without DW, and so do the properties of SC on the DW background. The upper critical field $H_{c2}$ in such a SC state strongly increases as the system approaches the critical pressure, where superconductivity first appears. $H_{c2}$ may considerably exceed its typical value without DW and has unusual upward curvature as function of temperature. The results obtained explain the experimental observations in layered organic superconductors (TMTSF)$_{2}$PF$_{6}$ and $α$-(BEDT TTF)$_{2}$KHg(SCN)$_{4}$.

description: The electromagnetic properties of the baryon decuplet are calculated in quenched QCD on a 20^3 x 40 lattice with a lattice spacing of 0.128 fm using the fat-link irrelevant clover (FLIC) fermion action with quark masses providing a pion mass as low as 300 MeV. Magnetic moments and charge radii are extracted from the electric and magnetic form factors for each individual quark sector. From these, the corresponding baryon properties are constructed. We present results for the higher order moments of the spin-3/2 baryons, including the electric quadrupole moment E2 and the magnetic octupole moment M3. The world's first determination of a non-zero M3 form factor for the Delta baryon is presented. With these results we provide a conclusive analysis which shows that decuplet baryons are deformed. We compare the decuplet baryon results from a similar lattice calculation of the octet baryons. We establish that the environment sensitivity is far less pronounced in the case of the decuplet baryons compared to that in the octet baryons. A surprising result is that the charge radii of the decuplet baryons are generally smaller than that of the octet baryons. The magnetic moment of the Delta^+ reveals a turn over in the low quark mass region, making it smaller than the proton magnetic moment. These results are consistent with the expectations of quenched chiral perturbation theory. A similar turn over is also noticed in the magnetic moment of the Sigma^*0, but not for Xi^* where only kaon loops can appear in quenched QCD. The electric quadrupole moment of the Omega^- baryon is positive when the negative charge factor is included, and is equal to 0.86 +- 0.12 x 10^-2 fm^2, indicating an oblate shape.

Year: 2012

description: The classical Steiner Problem may be stated: Given n points [formula omitted] in the Euclidean plane, to construct the shortest tree(s) (i.e. undirected, connected, circuit free graph(s)) whose vertices include [formula omitted]. The problem is generalised by considering sets in a metric space rather than points in E² and also by minimising a more general graph function than length, thus yielding a large class of network minimisation problems which have a wide variety of practical applications, The thesis is concerned with the following aspects of these problems. 1. Existence and uniqueness or multiplicity of solutions. 2. The structure of solutions and demonstration that minimising trees of various problems share common properties. 3. Solvability of problems by Euclidean constructions or by other geometrical methods.
