ALGEBRA SEMINAR
TIME: 3:35 - 4:25 p.m.
ROOM: Ayres B004
SPEAKER: Mr. Vajira Manathunga
TITLE: Arithmetic progressions in a UFD
In a series of talks Manathunga will present the proof of a recent (2012) generalization of Shivasankarnarayan Pillai's 16-theorem to UFDs.
PROBABILITY SEMINAR
TIME: 3:35 - 4:25 p.m.
ROOM: Ayres 112
SPEAKER: Dr. Olga L. Iziumtseva
TITLE: On regularization of the formal Fourier - Wiener transform of the self-intersection local time of planar Gaussian process
ABSTRACT: The Fourier--Wiener transform of the formal expression for a multiple self-intersection local time is described in terms of an integral, which is divergent on the diagonals. The method of regularization we used in this work is related to the regularization of functions with non integrable singularities. As an example, the problem of regularization is solved for a compactly perturbed Wiener process.
SIAM STUDENT CHAPTER SEMINAR
TIME: 3:30 - 4:25 p.m.
ROOM: Ayres 122
SPEAKER: Dr. Yetta Jager, ORNL
TITLE: Shaping seasonal flows for salmon and energy
Wednesday, October 3
MATH BIOLOGY SEMINAR
TIME: 10:10 - 11:00 a.m.
ROOM: Dabney 488
SPEAKER: Mr. Nathan Pollesch
TITLE: Introduction to R and data (chapter 4 of Bolker's book)
ANALYSIS SEMINAR
TIME: 3:35 - 4:30 p.m.
ROOM: Ayres 112
SPEAKER: Dr. Frank Martin, Faculty of Math and Informatics, Institute of Applied Analysis, University of Freiberg, Germany
TITLE: Discrete Boundary Value Problems and Circle Packings
ABSTRACT: In the talk classical boundary value problems in function theory and their solvability are presented. After a small introduction to circle packings discrete counterparts of these problems are introduced. Also analogue statements of their solvability are given. Furthermore an approach for solving
these problems is presented and will be illustrated by some examples. The talk is based on a joint work with Prof. E. Wegert, Prof. K. Stephenson and Dr. G. Semmler and is supported by the DFG grant We 1704/8-2.
Friday, October 5
COLLOQUIUM
TIME: 3:35 - 4:30 p.m.
ROOM: Ayres 405
SPEAKER: Prof. Jim Conant
TITLE: Homology of Aut(F_n)
ABSTRACT: We will outline recent beautiful developments in the theory of group homology. Although, the homology of a group is a classical construction, recent progress has shown it to be related to very modern mathematical developments such as quantum topology. Looking at one particular group, Aut(F_n), we show how algebraic spaces of decorated Feynman diagrams have been used to analyze its homology, showing it to be incredibly rich, with connections to modular forms.
Refreshments will be available at 3:15 p.m.
