SUMMARY:Derandomizing Algorithms via Spectral Graph Theory
DESCRIPTION:Speaker: Salil Vadhan (Harvard) \nTitle: Derandomizing Algorithms via Spectral Graph Theory\n\nAbstract: Randomization is a powerful tool for algorithms; it is often easier to design efficient algorithms if we allow the algorithms to “toss coins” and output a correct answer with high probability.  However\, a longstanding conjecture in theoretical computer science is that every randomized algorithm can be efficiently “derandomized” — converted into a deterministic algorithm (which always outputs the correct answer) with only a polynomial increase in running time and only a constant-factor increase in space (i.e. memory usage).  In this talk\, I will describe an approach to proving the space (as opposed to time) version of this conjecture via spectral graph theory.  Specifically\, I will explain how randomized space-bounded algorithms are described by random walks on directed graphs\, and techniques in algorithmic spectral graph theory (e.g. solving Laplacian systems) have yielded deterministic space-efficient algorithms for approximating the behavior of such random walks on undirected graphs and Eulerian directed graphs (where every vertex has the same in-degree as out-degree).  If these algorithms can be extended to general directed graphs\, then the aforementioned conjecture about derandomizing space-efficient algorithms will be resolved.\nJoint works with Jack Murtagh\, Omer Reingold\, Aaron Sidford\,  AmirMadhi Ahmadinejad\, Jon Kelner\, and John Peebles.

SUMMARY:Math\, Music and the Mind; Mathematical analysis of the performed Trio Sonatas of J. S. Bach
DESCRIPTION:Speaker: Daniel Forger (UMich)\n\nLocation: CMSA building\, 20 Garden Street\, Room G10\n\nTitle: Math\, Music and the Mind; Mathematical analysis of the performed Trio Sonatas of J. S. Bach\n\nAbstract: I will describe a collaborative project with the University of Michigan Organ Department to perfectly digitize many performances of difficult organ works (the Trio Sonatas by J.S. Bach) by students and faculty at many skill levels. We use these digitizations\, and direct representations of the score to ask how music should encoded in the mind. Our results challenge the modern mathematical theory of music encoding\, e.g.\, based on orbifolds\, and reveal surprising new mathematical patterns in Bach’s music. We also discover ways in which biophysical limits of neuronal computation may limit performance.

SUMMARY:Stability of spacetimes with supersymmetric compactifications
DESCRIPTION:Speaker: Lars Andersson (Max-Planck Institute for Gravitational Physics) \nTitle: Stability of spacetimes with supersymmetric compactifications \nAbstract: Spacetimes with compact directions\, which have special holonomy such as Calabi-Yau spaces\, play an important role in supergravity and string theory. In this talk I will discuss the global\, non-linear stability for the vacuum Einstein equations on a spacetime which is a cartesian product of a high dimensional Minkowski space with a compact Ricci flat internal space with special holonomy. I will start by giving a brief overview of related stability problems which have received a lot of attention recently\, including the black hole stability problem. This is based on joint work with Pieter Blue\, Zoe Wyatt\, and Shing-Tung Yau.
