A zero-free region of the Riemann zeta-function is a subset of the complex plane where the zeta-function is known to not vanish. In this talk we will discuss various computational and analytic techniques used to enlarge the zero-free region for the...

The main task of causal discovery is to learn direct causal relationships among observed random variables. These relationships are usually depicted via a directed graph whose vertices are the variables of interest and whose edges represent direct...

In this overview talk, I will present the encounter-based approach to diffusive processes in Euclidean domains and highlight its fundamental relation to the Steklov spectral problem. So, the Steklov eigenfunctions turn out to be particularly useful...

A good way to understand the structure of a finite group is through its representations. The family of representations of a group on a fixed field has several properties: it is closed by finite direct sums, by tensor products, it contains the dual...

Let G be a p-adic reductive group and k a field of characteristic p. The category Rep(G) of smooth k-linear representations is at the heart of the mod-p Langlands program. If we let I be a pro-p Iwahori subgroup of G, there is an associated...

Canada's First Student-Centric Quantum Conference Quantum Information Science and Technology (QIST) is an emerging interdisciplinary field poised to revolutionize various areas such as cryptography, communications, simulation, material discovery...

In combinatorial matrix theory (CMT) one studies properties of combinatorial matrices, i.e., matrices with entries 0, 1 and -1. For instance, permutation matrices, i.e., (0,1)-matrices with exactly one 1 in every row and column, are interesting...

Let $f(x)$ be a separable polynomial with rational number coefficients. In this talk I will review how the rational points of the hyperelliptic curve $y^2 = f(x)$ can sometimes be determined using the number field obtained by adjoining a root of $f$...

Characteristic classes are certain cohomology classes that we assign to vector bundles. In this talk, we will first familiarize ourselves with cohomology. We will go over singular cohomology of spaces, the cup product, the cap product, along with...

Strong cocomparability graphs are the reflexive graphs whose adjacency matrix can be rearranged by a simultaneous row and column permutation to avoid the submatrix with rows 01, 10. Strong cocomparability graphs form a subclass of cocomparability...
