This is the first of two talks in Algebraic K-theory. I will introduce the lower K-groups (0, 1 and 2) through the study of projective modules and their automorphisms, give a few examples and properties. The exact sequences that arise from the lower...

The summatory Mobius function M ( x ) is an important arithmetic function in number theory that contains information regarding primes and square-free numbers, and has strong links to the Riemann zeta function. Its growth rate is a difficult subject...

I will discuss how to formulate and prove a localization theorem for the virtual fundamental class of a moduli space with a relative perfect obstruction theory over a singular base. In the motivating example of the moduli space of stable log maps, I...

Students of grades 5 to 7 are invited to challenge and develop their thinking and creativity skills at the Math Circle Workshops. This is an enrichment program for students organized by the faculty members of the Department of Mathematics at the...

This talk will discuss traditional and modern approximation techniques for (expensive) derivative-free optimization, in which the approximation serves as a tool for identifying the optimality of the black-box objective, rather than merely...

We provide an inferential framework to assess variable importance for heterogeneous treatment effects. This assessment is especially useful in high-risk domains such as medicine, where decision makers hesitate to rely on black-box treatment...

As part of cell signalling, cells sense and respond to mechanical stimuli. This process is called mechanotransduction and is important in many functions of the cell, such as cell migration and tissue homeostasis. Although the biochemistry of cell...

I will review a topic in mathematical physics, called Lieb-Robinson bounds, that exemplifies analysis, geometry, and dynamics. These bounds describe the dynamics of a physical system of many interacting quantum degrees of freedom: they control how...

Abstract TBA

In this talk, I will talk about use of automata theory in answering problems in number theory. In 1844, Catalan conjectured that the set consisting of natural numbers of the form $2^n+1$, $n \ge 0$ and the set consisting of powers of $3$ has finite...
