Math & Stats Number Theory Seminar

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

Speaker: Ram Murty (¾ÅÐãÖ±²¥)

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 (¾ÅÐãÖ±²¥)

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 Queen’s University in 2009. He held postdoctoral positions at the University of California, San Diego, and at the University of Illinois at Urbana-Champaign. He joined Queen’s University 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 Queen’s as Professor of Mathematics with the Department of Mathematics and Statistics.
