description: The eT program is an open source electronic structure package with emphasis on coupled cluster and multilevel methods. It includes efficient spin adapted implementations of ground and excited singlet states, as well as equation of motion oscillator strengths, for CCS, CC2, CCSD, and CC3. Furthermore, eT provides unique capabilities such as multilevel Hartree-Fock and multilevel CC2, real-time propagation for CCS and CCSD, and efficient CC3 oscillator strengths. With a coupled cluster code based on an efficient Cholesky decomposition algorithm for the electronic repulsion integrals, eT has similar advantages as codes using density fitting, but with strict error control. Here we present the main features of the program and demonstrate its performance through example calculations. Because of its availability, performance, and unique capabilities, we expect eT to become a valuable resource to the electronic structure community.

Η σύζευξη αυτή αποκτά ακόμη πιο ενδιαφέροντα χαρακτήρα όταν προσεγγίζεται με τη βοήθεια της τεχνολογίας: χάρη στην επαυξημένη πραγματικότητα που τώρα δημιουργείται, οι θρυμματισμένες εικόνες περί κάλλους και αρτιμέλειας διογκώνονται, ενώ ενισχύεται η πολιτισμική ορατότητα του ανάπηρου σώματος δημιουργώντας με τον τρόπο αυτόν νέα συμφραζόμενα μεταξύ τέχνης και αναπηρίας.  Σκοπός αυτού του άρθρου είναι αρχικά να συζητήσει τις προκλήσεις, τα ερωτήματα αλλά και τις αντιφάσεις που θέτει η εξερεύνηση του τρίπτυχου περφόρμανς-αναπηρία-ψηφιακή εποχή στο έργο των «Εν Δυνάμει», της κολεκτίβας από καλλιτέχνες και καλλιτέχνιδες με ή χωρίς αναπηρία, με έδρα τη Θεσσαλονίκη. Υπό αυτό το πρίσμα, εστιάζω στις στρατηγικές επιλογές και ανησυχίες του Ανσάμπλ (δραματουργικές, αισθητικές και σκηνικές), οι οποίες αποδυναμώνουν τις κυρίαρχες αναπαραστάσεις του ανθρώπινου σώματος και ταυτόχρονα τις αντικαθιστούν με ένα νέο, τολμηρό σωματικό λεξιλόγιο, που αντλεί τη δύναμη και τη δυναμική του από την τεχνολογία.

How Does the Share of Imports Change During Structural Adjustment?

description: Estimating the price responsiveness of market shares during a period of structural transition requires a distinction to be made between responses to variables explicitly recognized in the model and those due to more general changes in the trading environment. Often the latter are minimally modelled as market penetration curves taking the form of a sigmoid trend. Broadly this is the approach followed in the present paper; however, the trend 'parameter' capturing ultimate market share at a fixed level of price competitiveness is itself made a logistic function of the logarithm of the relative price variable measuring such competitiveness. The application of the model is to quarterly data on the share of imports in Australian personal consumption over the 1980s and the first half of the 1990s. Most of the signal relevant to price competition between domestic and imported consumer goods occurred over the four years 1985-1988. This coincided with sizeable movements in the real exchange rate; and therefore, presumably, with collinear movements in the prices of the components within the domestic and the imported aggregates, which would be favourable circumstances for the application of Hicks' composite commodity idea. The responses in aggregate market shares during this episode suggest a very long-run Armington elasticity in the range 3.4 to 4.8, with short-run (quarterly) values of 0.6 to 0.8.

description: We have investigated the doping dependencies of the basal areas in single-layer high-T_c cuprates La_{2-x}Sr_xCuO_4 and HgBa_2CuO_x, as well as in two-layer Y_{1-y}Ca_yBa_2Cu_3O_x and HgBa_2CaCu_2O_x. The basal areas not only tend to shrink on hole doping, as expected from single electron quantum chemistry, but exhibit also a "bulge'' around optimum doping. We attribute the "bulge'' to the effects of the strongly correlated quantum liquid on the CuO_2 lattice, rendering it nearly incompressible around optimum doping, but highly compressible in the weakly overdoped regime. Inhomogenous doping cannot account for this anomaly in the electronic compressibility of the CuO_2 lattice.

description: Το 2010 η ομάδα Nova Melancholia δημιούργησε την παράσταση Πένθος και Μελαγχολία, βασισμένη στο ομώνυμο κείμενο του Sigmund Freud. Στο τέλος της παράστασης εμφανιζόταν στη σκηνή η Σάντρα Νούλα, η μητέρα του σκηνοθέτη Βασίλη Νούλα, και, μεταξύ άλλων, τραγουδούσε πλέι μπακ το Gloomy Sunday στη διασκευή της Diamanda Galás. Το 2018 στην παράσταση Spleen της ίδιας ομάδας τρεις ηθοποιοί τραγουδούν πλέι μπακ το ίδιο ακριβώς τραγούδι παραπέμποντας στην παρουσία της Σάντρας Νούλα στην παράσταση του 2010, ενώ η Σάντρα έχει, στο μεταξύ, πεθάνει ξαφνικά. Τέλος, το 2022 στην παράσταση “Marcel Duchamp” της Nova Melancholia τρεις ηθοποιοί τραγουδούν και πάλι πλέι μπακ το Gloomy Sunday στη διασκευή της Diamanda Galás, ενώ στα μόνιτορ δεξιά και αριστερά προβάλλεται το απόσπασμα από την  πρώτη παράσταση Πένθος και Μελαγχολία. Τα τρία αυτά στιγμιότυπα, αν ερμηνευτούν αλληλοσυνδεόμενα, αποκαλύπτουν μια τελείως ιδιαίτερη συνθήκη αναπαραστάσεων: Το «πρωτότυπο» (η Σάντρα Νούλα της πρώτης παράστασης) έχει, κυριολεκτικά, πεθάνει. Οι επόμενες παραστάσεις επιμένουν να αναφέρονται με διαφορετικούς τρόπους στο πρόσωπο/σώμα/υποκείμενο που πια δεν υπάρχει, παρά ως ανάμνηση μιας, ούτως ή άλλως φευγαλέας, επιτέλεσης.

Κάποια από τα ερωτήματα που ανακύπτουν και που θα προσπαθήσω να προσεγγίσω είναι τα ακόλουθα: i. Ποιες σημασίες προσδίδονται στην παρουσία του υποκειμένου στην πρώτη παράσταση μέσω των αναπαραστάσεών του; ii. Με ποιους τρόπους και ποια ειδικά χαρακτηριστικά υπεισέρχεται στις παραστάσεις μια θανατογραφική διάσταση; iii. Εκκινώντας από το γεγονός ότι στην πρώτη παράσταση το πρόσωπο που παρίσταται είναι ο ρόλος του (η Σάντρα Νούλα δεν αναπαριστά με τη στενή έννοια του όρου, αλλά εμφανίζεται ως η εαυτή της), ποια αισθητική (και ποια ηθική) της αναπαράστασης διατυπώνεται στις παραστάσεις;

description: This paper presents a detailed assessment of the medium term outlook for the demand for labour in Australia. Forecasts are reported for employment by industry, by occupation, by State and Territory, by hours worked and by skill level. The forecasts are driven, in the first instance, by a fully articulated view about the outlook for the macroeconomy. This macro view is then combined with projections for various industry specific variables prepared by relevant expert organisations. Coherence between the different sources is ensured by incorporating them in a single simulation using the MONASH model, a large applied general equilibrium model of the Australian economy. In deriving the forecasts, attention has been paid to the effect of technological and social change on the structure of the economy in recent years , and to the implications of that change for future labour demand. The paper deals particularly with technical change which affects the distribution of employment across occupations within industries, and the distribution across different categories of hours worked within occupations. Tables are included to illustrate how the forecasting system can be interrogated to reveal • the contributions of various industries to employment growth for a selected occupation, and • the relative importance of output growth, capital growth and labour saving technical change to industry employment growth. The paper concludes with a review of some issues associated with making a proper assessment of the forecasts.
Potential for ill-posedness in several 2nd-order formulations of the Einstein equations

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: Second-order formulations of the 3+1 Einstein equations obtained by eliminating the extrinsic curvature in terms of the time derivative of the metric are examined with the aim of establishing whether they are well posed, in cases of somewhat wide interest, such as ADM, BSSN and generalized Einstein-Christoffel. The criterion for well-posedness of second-order systems employed is due to Kreiss and Ortiz. By this criterion, none of the three cases are strongly hyperbolic, but some of them are weakly hyperbolic, which means that they may yet be well posed but only under very restrictive conditions for the terms of order lower than second in the equations (which are not studied here). As a result, intuitive transferences of the property of well-posedness from first-order reductions of the Einstein equations to their originating second-order versions are unwarranted if not false.

Why do expiring futures and cash prices diverge for grain markets?
Creators: name: Aulerich, Nicole M.
name: Fishe, Raymond P.H.
name: Harris, Jeffrey
Publisher: name: American University
Year: 2023

description: In recent years, cash and futures prices have failed to converge at expiration for selected corn, soybean and wheat commodity contracts. This lack of convergence raises questions about the effectiveness of arbitrage activities, and increases concerns about the usefulness of these contracts for hedging. We describe the delivery process for these contracts, and show that it embeds a valuable real option on the long side—the option to exchange the deliverable for another futures contract. As the relative volatility of cash and futures prices increases, this option increases in value, which disconnects the cash market from the deliverable instrument in a futures contract. Our estimates of this option’s value show that it may create significant price divergence. We parameterize an option pricing model using data on these three commodities from 2000 to 2008 and show that the option model fits closely to recent episodes of non-convergence, which lends support to the importance of real option effects.

description: Fake news spread widely on social media in various domains, which lead to real-world threats in many aspects like politics, disasters, and finance. Most existing approaches focus on single-domain fake news detection (SFND), which leads to unsatisfying performance when these methods are applied to multi-domain fake news detection. As an emerging field, multi-domain fake news detection (MFND) is increasingly attracting attention. However, data distributions, such as word frequency and propagation patterns, vary from domain to domain, namely domain shift. Facing the challenge of serious domain shift, existing fake news detection techniques perform poorly for multi-domain scenarios. Therefore, it is demanding to design a specialized model for MFND. In this paper, we first design a benchmark of fake news dataset for MFND with domain label annotated, namely Weibo21, which consists of 4,488 fake news and 4,640 real news from 9 different domains. We further propose an effective Multi-domain Fake News Detection Model (MDFEND) by utilizing a domain gate to aggregate multiple representations extracted by a mixture of experts. The experiments show that MDFEND can significantly improve the performance of multi-domain fake news detection. Our dataset and code are available at https://github.com/kennqiang/MDFEND-Weibo21.

description: Radiative communication using electromagnetic fields is the backbone of today's wirelessly connected world, which implies that the physical signals are available for malicious interceptors to snoop within a 5-10 m distance, also increasing interference and reducing channel capacity. Recently, Electro-quasistatic (EQS) human body communication was demonstrated which utilizes the human body's conductive properties to communicate without radiating the signals outside the body. Previous experiments showed that an attack with an antenna is unsuccessful, more than 1 cm of the body surface and 15 cm of an EQS-HBC device. However, since this is a new communication modality, it calls for investigation of new attack modalities - that can potentially exploit the physics utilized in the EQS-HBC to break the system. In this study, we present a novel attack method for EQS-HBC devices, using the body of the attacker itself as a coupling surface and capacitive inter-body coupling between the user and the attacker. We develop theoretical understanding backed by experimental results for inter-body coupling, as a function of distance between the subjects. We utilize this newly developed understanding to design EQS-HBC transmitters to minimize the attack distance through inter-body coupling as well as minimize the interference among multiple EQS-HBC users due to inter-body coupling. This understanding allows us to develop more secure and robust EQS-HBC based body area networks in the future.

description: Πέρα από ιατρικό επίτευγμα, η δωρεά και η μεταμόσχευση οργάνων είναι μια πολιτισμική ιστορία που απέρριψε ταμπού και προχώρησε σε εννοιολογικούς επαναπροσδιορισμούς. Αγγίζει ζητήματα καίρια, όπως η σχέση ανθρώπου και μηχανής, ανθρώπου και ζώου ή τα όρια μεταξύ ζωής και θανάτου, μεταξύ των φύλων και των εθνοτήτων. Τέτοια όρια γίνονται ρευστά όταν συνδέονται με τη δωρεά και τη μεταμόσχευση οργάνων, και στον 21ο αιώνα έχουν πια αρχίσει να απασχολούν το θέατρο και την performance.

Με αφετηρία την performance The Body is a Big Place των Αυστραλών Peta Clancy και Helen Pynor (2011), όπου πρωταγωνίστριες είναι δύο καρδιές χοίρων, στόχο έχουμε να δείξουμε ότι η δωρεά και η μεταμόσχευση οργάνων ως (ανα)παράσταση ξαναθέτει το ερώτημα «Τι είναι και τι δεν είναι ανθρώπινο σώμα;», επομένως «Τι είναι ηθοποιός και τι δεν είναι;». Στη θέση των παραδοσιακών αυτών δραματικών εννοιών ή/και μεταδραματικών διαδικασιών αναδύεται ένα οντολογικά ασταθές σώμα, που συνιστά «πεδίο αισθητικών, βιοπολιτικών, ηθικών και οικονομικών διενέξεων στον 21ο αιώνα».  Έτσι, περνάμε από τον άνθρωπο-υποκείμενο, ως πρωταγωνιστή στο θέατρο, στο συμπαγές όργανο χωρίς σώμα, την καρδιά, που χάρη στη δωρεά και τη μεταμόσχευση γίνεται πρωταγωνίστρια στη μεταουμανιστική σκηνή της ζωής και της τέχνης.

description: Two dimensional SPH simulations of a precessing accretion disc in a q=0.1 binary system (such as XTE J1118+480) reveal complex and continuously varying shape, kinematics, and dissipation. The stream-disc impact region and disc spiral density waves are prominent sources of energy dissipation.The dissipated energy is modulated on the period P_{sh} = ({P_{orb}}^{-1}-{P_{prec}}^{-1}^{-1} with which the orientation of the disc relative to the mass donor repeats. This superhump modulation in dissipation energy has a variation in amplitude of ~10% relative to the total dissipation energy and evolves, repeating exactly only after a full disc precession cycle. A sharp component in the light curve is associated with centrifugally expelled material falling back and impacting the disc. Synthetic trailed spectrograms reveal two distinct "S-wave" features, produced respectively by the stream gas and the disc gas at the stream-disc impact shock. These S-waves are non-sinusoidal, and evolve with disc precession phase. We identify the spiral density wave emission in the trailed spectrogram. Instantaneous Doppler maps show how the stream impact moves in velocity space during an orbit. In our maximum entropy Doppler tomogram the stream impact region emission is distorted, and the spiral density wave emission is uppressed. A significant radial velocity modulation of the whole line profile occurs on the disc precession period. We compare our SPH simulation with a simple 3D model: the former is appropriate for comparison with emission lines while the latter is preferable for skewed absorption lines from precessing discs.

description: For general gravitational collapse, inside the black-hole region, singularities $(r=0)$ may arise. In this article, we aim to answer how strong these singularities could be. We analyse the behaviours of various geometric quantities. In particular, we show that in the most singular scenario, the Kretschmann scalar obeys polynomial blow-up upper bounds $O(1/r^N)$. This improves previously best-known double-exponential upper bounds $O\big(\exp\exp(1/r)\big)$. Our result is sharp in the sense that there are known examples showing that no sub-polynomial upper bound could hold. Finally we do a case study on perturbations of the Schwarzschild solution.

description: Κινούμενο μεταξύ κριτικής ανάλυσης και επιτελεστικής γραφής, το άρθρο αντλεί υλικό από την πολυετή καλλιτεχνική μου έρευνα πάνω στην Πρακτική της Δημοκρατίας, προκειμένου να συζητήσει τη λειτουργία των παραστατικών τεχνών σήμερα ως μια πράξη δημιουργίας δημόσιου χώρου, μια πράξη «publicing». Η θεωρητικός Rebecca Schneider ορίζει την πολιτική ως την ενσώματη πρακτική τού να «εμφανίζομαι δημόσια στους άλλους όπως εκείνοι εμφανίζονται [σε μένα]», συνδέοντάς την έτσι άμεσα με τις παραστατικές τέχνες.
Με έναυσμα τις ιδέες της Schneider, το άρθρο εστιάζει στη διερεύνηση του τρόπου με τον οποίο συμμετοχικές δομές τέχνης δύνανται να επανενεργοποιήσουν τον δημόσιο χώρο. Δεδομένης της σοβαρής κρίσης που υφίσταται σήμερα η δημοκρατία στον δυτικό κόσμο, η πολιτική φιλόσοφος Chantal Mouffe συζητά την κρίσιμη συμβολή της τέχνης στην επείγουσα αυτή προσπάθεια. Μέσα από τις ενσώματες συνδέσεις που προτείνει η τέχνη, σημειώνει η Mouffe, δημιουργούνται δημόσιες μορφές συλλογικών σωμάτων που διαταράσσουν τον ‘κανονικό’ ρυθμό των πόλεων. Επανασυνδέοντας την πρακτική της δημοκρατίας με την υλικότητα του σώματος, προσεγγίζοντας πολιτικές πρακτικές μέσω των αισθήσεων και των προσωπικών εμπειριών και ιστοριών, οι συμμετοχικές δομές τέχνης μπορούν να ανοίξουν χώρο σε νέα κοινωνικά μοντέλα συνύπαρξης, διαφορετικά από τα κυρίαρχα καπιταλιστικά, με τρόπο που αλλιώς δεν είναι δυνατός.

description: Το άρθρο αποτελεί μια βιωματική, behind-the-scenes αποτίμηση της παράστασης θεάτρου ντοκιμαντέρ PIETÀ, η οποία διερευνά το προσωπικό και συλλογικό τραύμα της γυναικοκτονίας μέσα από την ουσιαστική συμβολή των μητέρων πέντε δολοφονημένων γυναικών. Στο άρθρο, η σκηνοθέτις-δραματουργός της PIETÀ επικοινωνεί τις διαπροσωπικές σχέσεις που προηγούνται κι έπονται της σύντομης ζωής μιας παράστασης του θεάτρου του πραγματικού, καθώς και τις ηθικές, μεθοδολογικές και δημιουργικές προκλήσεις που συνεπάγεται η μεταγραφή του τραύματος της έμφυλης βίας σε δραματουργικό υλικό και ακολούθως σε σκηνική επιτέλεση. Παράλληλα, το άρθρο εστιάζει στην πολιτική διάσταση του συναισθήματος, τοποθετώντας τη μητρότητα στο φως μιας έμφυλης πολιτειότητας που διαρρηγνύει τις πατριαρχικές ταξινομήσεις του οικιακού (θήλυ) και του πολιτικού (άρρεν) και αναδεικνύει την ενδυναμωτική, χειραφετητική ισχύ του συναισθήματος όπως αυτή αναδύεται μέσα από τη μετασχηματιστική δυναμική της απώλειας και του πένθους, τους έμφυλους δεσμούς αλληλοφροντίδας και αλληλεγγύης και τις συλλογικές διεκδικήσεις για ισότητα και κοινωνική δικαιοσύνη. Θέτοντας στο επίκεντρο τις σκηνικές τροπικότητες της ευαλωτότητας, της βιωμένης εμπειρίας, της μνήμης και της μαρτυρίας, το άρθρο αναλύει και προτείνει μια πολυφωνική και θραυσματική ενσώματη δραματουργία, η οποία διασταυρώνεται με τα διακυβεύματα της κριτικής φεμινιστικής θεωρίας και των σπουδών φύλου, αντλώντας από τις επιστημολογικές αναζητήσεις της «συναισθηματικής στροφής».

description: We suggest a new large-N_c limit for multi flavor QCD. Since fundamental and two-index antisymmetric representations are equivalent in SU(3), we have the option to define SU(N_c) QCD keeping quarks in the latter. We can then define a new 1/N_c expansion (at fixed number of flavors N_f) that shares appealing properties with the topological (fixed N_f/N_c) expansion while being more suitable for theoretical analysis. In particular, for N_f=1, our large-N_c limit gives a theory that we recently proved to be equivalent, in the bosonic sector, to N=1 supersymmetric gluodynamics. Using known properties of the latter, we derive several qualitative and semi-quantitative predictions for N_f=1 massless QCD which can be easily tested in lattice simulations. Finally, we comment on possible applications for pure SU(3) Yang-Mills theory and real QCD.

description: We investigate local and global properties of the one-dimensional Bose-Hubbard model with an external confining potential, describing an atomic condensate in an optical lattice. Using quantum Monte Carlo techniques we demonstrate that a local-density approximation, which relates the unconfined and the confined model, yields quantitatively correct results in most of the interesting parameter range. We also examine claims of universal behavior in the confined system, and demonstrate the origin of a previously calculated fine structure in the experimentally accessible momentum distribution.

description: Radiative transfer describes the propagation of electromagnetic radiation through an interacting medium. This process is often simulated by the use of the Monte Carlo method, which involves the probabilistic determination and tracking of simulated photon packages. In the regime of high optical depths, this approach encounters difficulties since a proper representation of the various physical processes can only be achieved by considering high numbers of simulated photon packages. As a consequence, the demand for computation time rises accordingly and thus practically puts a limit on the optical depth of models that can be simulated. Here we present a method that aims to solve the problem of high optical depths in dusty media, which relies solely on the use of unbiased Monte Carlo radiative transfer. For that end, we identified and precalculated repeatedly occuring and simulated processes, stored their outcome in a multidimensional cumulative distribution function, and immediately replaced the basic Monte Carlo transfer during a simulation by that outcome. During the precalculation, we generated emission spectra as well as deposited energy distributions of photon packages traveling from the center of a sphere to its rim. We carried out a performance test of the method to confirm its validity and gain a boost in computation speed by up to three orders of magnitude. We then applied the method to a simple model of a viscously heated circumstellar disk, and we discuss the necessity of finding a solution for the optical depth problem with regard to a proper temperature calculation. We find that the impact of an incorrect treatment of photon packages in highly optically thick regions extents even to optically thin regions, thus, changing the overall observational appearance of the disk.

description: Biomedical research papers use significantly different language and jargon when compared to typical English text, which reduces the utility of pre-trained NLP models in this domain. Meanwhile Medline, a database of biomedical abstracts, introduces nearly a million new documents per-year. Applications that could benefit from understanding this wealth of publicly available information, such as scientific writing assistants, chat-bots, or descriptive hypothesis generation systems, require new domain-centered approaches. A conditional language model, one that learns the probability of words given some a priori criteria, is a fundamental building block in many such applications. We propose a transformer-based conditional language model with a shallow encoder "condition" stack, and a deep "language model" stack of multi-headed attention blocks. The condition stack encodes metadata used to alter the output probability distribution of the language model stack. We sample this distribution in order to generate biomedical abstracts given only a proposed title, an intended publication year, and a set of keywords. Using typical natural language generation metrics, we demonstrate that this proposed approach is more capable of producing non-trivial relevant entities within the abstract body than the 1.5B parameter GPT-2 language model.

description: The University of British Columbia Food Systems Project has been developed to increase the sustainability of the UBC food system. One of the main objectives of this project is the re-localization of the food system. Therefore, our task in 2005 was to develop a survey that determines 1) whether or not, and to what extent, the University of British Columbia’s population is willing to buy local foods and 2) if a high interest is indicated to purchase local foods, whether or not the UBC’s population is willing to pay more for it. This is an important aspect of determining how to proceed with re-localization of the food system. A draft survey was developed from sample questions provided by previous AgSci 450 and Sauder School of Business students as well as discussions within our group. The original survey was submitted to the 2005 AgSci 450 class for suggestions and completion. Based on their responses, the questionnaire was revised again and used to survey a small sample population across campus and again the AgSci 450 class. Often the answers received from the AgSci 450 class were slightly different from the small sample population across campus. This enforced the importance of testing the draft survey on a small sample of the perspective population when developing a quality survey. The results were then used to further evaluate the questionnaire and develop suggestions for the 2006 AgSci 450 class.

description: Based on numerical simulations, a study of the high temperature, finite frequency, thermal conductivity $κ(ω)$ of spin-1/2 ladders is presented. The exact diagonalization and a novel Lanczos technique are employed.The conductivity spectra, analyzed as a function of rung coupling, point to a non-diverging $dc-$limit but to an unconventional low frequency behavior. The results are discussed with perspective recent experiments indicating a significant magnetic contribution to the energy transport in quasi-one dimensional compounds.

description: We study machine learning of phenomenologically relevant properties of string compactifications, which arise in the context of heterotic line bundle models. Both supervised and unsupervised learning are considered. We find that, for a fixed compactification manifold, relatively small neural networks are capable of distinguishing consistent line bundle models with the correct gauge group and the correct chiral asymmetry from random models without these properties. The same distinction can also be achieved in the context of unsupervised learning, using an auto-encoder. Learning non-topological properties, specifically the number of Higgs multiplets, turns out to be more difficult, but is possible using sizeable networks and feature-enhanced data sets.

title: Quasiperiodic Renormalisation: Quasiperiodic Sums, Products and Composition Sum Operators
Creators: name: Verschueren, Paul
Publisher: name: The Open University
Year: 2016

description: We study two topics in the renormalisation group theory of quasiperiodic systems, both topics having a number of important applications. Firstly we apply renormalisation techniques to a family of functions we designate quasiperiodic sums and products. These functions link the study of critical phenomena in diverse fields such as the emergence of strange non-chaotic attractors, critical KAM theory, convergence of ergodic averages, and q-series (much used in string theory). In pure mathematics they have also been studied extensively in complex power series analysis, partition theory, and Diophantine approximation. We set these currently dispersed results within a unified framework, and develop a more systematic approach to three key examples. We improve significantly on a series of number-theoretic results obtained by Sierpinsky, Hardy, Hecke, Lang et al; we provide a rigorous proof of some empirically obtained results recently reported by Knill et al (2011-12); and we settle (negatively) an open question of Erdos-Szekeres-Lubinsky dating initially from 1959. Secondly we study the fixed points of quasiperiodic renormalisation. These arise in the study of the Harper equation (almost Mathieu equation), barrier billiards, and a number of other scenarios. We identify the natural setting for their study as a certain class of linear operators (composition sum operators) acting on unbounded (non-Banach) function spaces. We develop the necessary foundations for this theory, and then apply it to construct the space of all fixed points of the golden renormalisation whose singularities are either poles, essential singularities, or logarithmic singularities of a certain simple type. This fixed point space is shown to include previously unknown fixed points.
