HITCHIN CONNECTION ON THE VEECH CURVE SHEHRYAR SIKANDER Abstract. We give an expression for the pull back of the Hitchin connection from the moduli space of genus two curves to a ten-fold covering of a Teichm¨ullercurve discovered by Veech. We then give an expression, in terms of iterated integrals, for the monodromy representation of this connection. As a corollary we obtain quantum representations of infinitely many pseudo-Anosov elements in the genus two mapping class group. Contents 1. Introduction 2 1.1. Acknowledgements 6 2.

Orbital Resonances and GPU Acceleration of Binary Black Hole Inspiral Simulations
Orbital resonances and GPU acceleration of binary black hole inspiral simulations by Adam Gabriel Marcel Lewis A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy Department of Physics University of Toronto c Copyright 2018 by Adam Gabriel Marcel Lewis Abstract Orbital resonances and GPU acceleration of binary black hole inspiral simulations Adam Gabriel Marcel Lewis Doctor of Philosophy Department of Physics University of Toronto 2018 Numerical relativity, the direct numerical integration of the Einstein field equations, is now a mature subfield of computational physics, playing a critical role in the generation of signal templates for comparison with data from ground-based gravitational wave de- tectors. The application of numerical relativity techniques to new problems is at present complicated by long wallclock times and intricate code. In this thesis we lay groundwork to improve this situation by presenting a GPU port of the numerical relativity code SpEC. Our port keeps code maintenance feasible by relying on various layers of automation, and achieves high performance across a variety of GPUs. We secondly introduce a C++ soft- ware package, TLoops, which allows numerical manipulation of tensors using single-line C++ source-code expressions resembling familiar tensor calculus notation. These expres- sions may be compiled and executed immediately, but also can be used to automatically generate equivalent GPU or low-level CPU code, which then executes in their place. The GPU code in particular achieves near-peak performance. Finally, we present simulations of eccentric binary black holes. We develop new methods to extract the fundamental fre- quencies of these systems. -

The distance formula in noncommutative geometry was introduced Small-Data Solutions to by Connes at the end of the 1980s. It is a generalization of Riemannian 3D Quasilinear Wave geodesic distance that makes sense in a noncommutative setting, and provides an original tool to study the geometry of the space of Equations states on an algebra. It also has an intriguing echo in physics, for it yields a metric interpretation for the Higgs field. In the 1990s, Jared Speck, Massachusetts Rieffel noticed that this distance is a noncommutative version of the Institute of Technology, Cambridge, Wasserstein distance of order 1 in the theory of optimal transport. MA More exactly, this is a noncommutative generalization of Kantorovich dual formula of the Wasserstein distance. Connes distance thus offers In 1848 James Challis showed that an unexpected connection between an ancient mathematical problem smooth solutions to the compressible and the most recent discovery in high energy physics. -

In three spatial dimension, we study the Cauchy problem for the wave equation 2 P ∂t Ψ+(1+Ψ) ∆Ψ = 0 for P 1, 2 . We exhibit a form of stable Tricomi-type degen- eracy− formation that has not previously∈ { } been studied in more than one spatial dimension. Specifically, using only energy methods and ODE techniques, we exhibit an open set of data such that Ψ is initially near 0 while 1 + Ψ vanishes in finite time. In fact, generic data, when appropriately rescaled, lead to this phenomenon. The solution remains regular in the following sense: there is a high-order L2-type energy, featuring degenerate weights only at the top-order, that remains bounded. When P = 1, we show that any C1 extension of Ψ to the future of a point where 1+Ψ = 0 must exit the regime of hyperbolicity. Moreover, the Kretschmann scalar of the Lorentzian metric corresponding to the wave equation blows up at those points. -

Honors and Awards Recipients, One of My Favorite Commencement Traditions Is Recognizing the Academic Excellence of Our Students During the Honors and Awards Program
onors and wards H 2021A HonorsINTRODUCTION and Awards Dr. Michele Gillespie, Dean, Wake Forest College To our 2021 College Honors and Awards recipients, One of my favorite Commencement traditions is recognizing the academic excellence of our students during the Honors and Awards program. While we are unable to celebrate together in-person this year, I want to congratulate our students for their impressive achievements in the arts, humanities, social sciences, and sciences through this commemorative program. The honors and awards listed here represent thousands of hours of research, scholarship, and critical thinking. These students have demonstrated intellectual leadership, contributed to the creation of new knowledge, expressed themselves creatively through different mediums, and produced strikingly original scholarship. Class of 2021, you have fulfilled the mission that we set before you when you first stood in Wait Chapel during opening convocation four years ago. We told you then to use your liberal arts education to build a pro humanitate spirit that will let you make the world a better place for all. Your intellectual curiosity, passion for knowledge, and concern for others inspires all around you, including your parents, your faculty, and me. Thank you to our faculty for carefully guiding these students along the path to academic excellence. Parents and families, I salute your efforts as well. You have been beacons of love and support. I know we are all proud of these students because they know how to ask critical questions. “The power to question,” Indira Gandhi observed, “is the basis of all human progress.” May you continue to question our world, and to use knowledge to change what you do not like in our world so you can make it better. -

A Proof of Price's Law for the Collapse of a Self-Gravitating Scalar Field
A proof of Price’s law for the collapse of a self-gravitating scalar field Mihalis Dafermos∗and Igor Rodnianski† October 23, 2018 Abstract A well-known open problem in general relativity, dating back to 1972, has been to prove Price’s law for an appropriate model of gravitational collapse. This law postulates inverse-power decay rates for the gravita- tional radiation flux on the event horizon and null infinity with respect to appropriately normalized advanced and retarded time coordinates. It is intimately related both to astrophysical observations of black holes and to the fate of observers who dare cross the event horizon. In this paper, we prove a well-defined (upper bound) formulation of Price’s law for the collapse of a self-gravitating scalar field with spherically symmetric initial data. We also allow the presence of an additional gravitationally coupled Maxwell field. Our results are obtained by a new mathematical technique for understanding the long-time behavior of large data solutions to the resulting coupled non-linear hyperbolic system of p.d.e.’s in 2 indepen- dent variables. The technique is based on the interaction of the conformal geometry, the celebrated red-shift effect, and local energy conservation; we feel it may be relevant for the problem of non-linear stability of the Kerr solution. When combined with previous work of the first author concerning the internal structure of charged black holes, which assumed the validity of Price’s law, our results can be applied to the strong cos- arXiv:gr-qc/0309115v3 9 Nov 2004 mic censorship conjecture for the Einstein-Maxwell-real scalar field system with complete spacelike asymptotically flat spherically symmetric initial data.
