Events for 10/11/2017 from all calendars
Student Working Seminar in Groups and Dynamics
Time: 1:00PM - 2:00PM
Location: BLOC 628
Speaker: Mehrzad Monzavi/Konrad Wrobel
Title: Shannon's Entropy II
Abstract: We will finish talking about basic properties of entropy and discuss concentration bounds, the equipartition property and if time permits, the Shannon's Fundamental Theorem for a Noiseless Channel.
Noncommutative Geometry Seminar
Time: 2:00PM - 3:00PM
Location: BLOC 628
Speaker: Benben Liao, Texas A&M University
Title: Noncommutative maximal inequalities for group actions
Abstract: Let $G$ be a finitely generated group, and $M$ a semi-finite von Neumann algebra on which $G$ acts. When the group $G$ has polynomial growth, we obtain strong type $(p,p),p>1,$ and weak type $(1,1)$ maximal inequalities for $G$ acting on $M$. The result extends the work of Yeadon and Junge-Xu for $G$ being the integer group. This is based on joint work with Guixiang Hong and Simeng Wang (https://arxiv.org/abs/1705.04851).
Groups and Dynamics Seminar
Time: 3:00PM - 4:00PM
Location: BLOC 220
Speaker: Rostislav Grigorchuk, Texas A&M
Title: On spectra of groups of intermediate growth
Abstract: I will explain how to compute the spectrum of the discrete Laplacian on a Cayley graph of the group of intermediate growth constructed by me in 1980 (joint result with A.Dudko). Also, the case of the so called overgroup of intermediate growth will be discussed. The arguments will be based on a combination of results from algebra, representation theory, graph theory and classical harmonic analysis. This talk is intended to be easy for the audience, and everything will be quite elementary. The talk could also be considered as a preparation for a second, more advanced future talk of the speaker at GD seminar.
Postdoc Colloquium Series
Time: 4:00PM - 5:00PM
Location: Bloc 220
Speaker: Isaac Harris , TAMU
Title: Inverse scattering for materials with a conductive boundary
Abstract: In this talk, we will consider the inverse scattering problem for a material with a conductive boundary. We will see that the shape of the object can be uniquely determined by the scattering data. Next, we turn our attention to the associated transmission eigenvalue problem. The transmission eigenvalue problem corresponds to a differential operator that contains the material parameters and therefore hold information about the coefficients.
AMUSE
Time: 6:00PM - 00:00AM
Location: BLOC 220
Speaker: Dr. Alireza Talebpour, Texas A&M University, Department of Civil Engineering
Title: Autonomous Vehicles: Challenges and Opportunities
Abstract: Driverless cars will appear on our roads and there is no question about that. The only question is "when?". To answer this question, we need to find a solution to several issues associated with this technology, including public acceptance and safety concerns. In this presentation, we will discuss the possible impacts of driverless cars on our lives, while a special focus will be made on the safety concerns.
