The theta process is a stochastic process of number theoretical origin arising from a scaling limit of quadratic Weyl exponential sums. It shares many properties in common with the Brownian motion such as its Hölder continuity, covariance structure...

In the talk exchangeability appears in two different meanings. In the first part, the determination of the phase diagram of the Curie-Weiss model relies on De Finetti’s Theorem. The Curie-Weiss distribution will be expressed as a random mixture of...

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...

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...

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...

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...

Limits and colimit constructions are ubiquitous in category theory, and are one of the main tools used to understand how objects in a category relate to one another. These are very concrete and easily stated in terms of universal properties: given a...

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...
