Math & Stats Number Theory Seminar
Thursday, September 12, 2024

Time: 4:00 p.m.  Place: Jeffery Hall, Room 202

Speaker: Ram Murty (Queen's University)

Title: The Partition Function Revisited via Probability

Abstract: In 1918, Hardy and Ramanujan derived the asymptotic behavior of the partition function using the complicated circle method. In 1997, Baez-Duarte derived the same formula simply using ideas of probability theory and the central limit theorem. I will discuss this paper and give an informal presentation of the key ideas.

Speaker: Anna Parlak (UC Davis)

Title: Pseudo-Anosov homeomorphisms and their suspension flows

Abstract: The most interesting homeomorphisms of surfaces are the ones that are pseudo-Anosov. They are characterized by the existence of a pair of singular foliations whose leaves are respectively stretched or contracted under the homeomorphism. In this talk, I will discuss the key properties of pseudo-Anosov homeomorphisms and their suspension flows on three-manifolds that fiber over the circle.

Math & Stats Department Colloquium
Friday, September 6, 2024

Time: 2:30 p.m.  Place: Jeffery Hall, Room 234

Speaker: Bahman Gharesifard (Queen's University)

Title: Universal Approximation

Abstract: Bahman Gharesifard will provide a historical overview of the universal approximation theory for neural networks and offer some geometric results for the challenging case of deep neural networks, which have bounded width.

Bio: Bahman Gharesifard obtained his Ph.D. in Mathematics from ºÚÁϳԹÏ×ÊÔ´ in 2009. He held postdoctoral positions at the University of California, San Diego, and at the University of Illinois at Urbana-Champaign. He joined ºÚÁϳԹÏ×ÊÔ´ from 2013 to 2021, and was an Alexander von Humboldt Foundation Fellow at the University of Stuttgart from 2019-2020. He then moved to University of California, Los Angeles, as Professor with the Electrical & Computer Engineering Department. In 2024, he re-joined ºÚÁϳԹÏ×ÊÔ´ as Professor of Mathematics with the Department of Mathematics and Statistics.
