Classically, Dieudonné theory offers a linear algebraic classification of finite group schemes and p-divisible groups over a perfect field of characteristic p>0. In this talk, I will discuss generalizations of this story from the perspective of p...

Counting lattice paths with unit up and right steps beginning at the origin that are somehow constrained by a boundary is an old problem. When the boundary is the line y=x the celebrated Chung-Feller theorem states the number of paths having k flaws...

We put forward two principles of decoupling, aiming to provide a new algebraic approach of reducing decoupling for new manifolds to decoupling for known manifolds. This is joint with Jianhui Li.

Several years ago, Dr Kathryn Isaac, a UBC professor and clinical surgeon contacted me with an intriguing problem. In her work on cosmetic reconstructive for post-breast-cancer-surgery patients, she encounters cases of failure that result (weeks or...

Originally distributions were introduced in PDE-theory to generalize the notion of functions. However, this analytical concept also has some purely algebraic properties, which are worth considered. In particular, they are an important example of...

For centuries, mathematicians have relied on computers to perform calculations, to suggest conjectures, and as components of mathematical proofs. In the light of more modern tools such as interactive theorem provers, machine learning algorithms, and...

Directorate Open-house We invite you to meet with our PIMS Directors and review current and future PIMS scientific and educational funding opportunities. Time 12:00 PM Pacific/ 1:00 PM Mountain/ 3:00 PM Eastern.

This talk introduces a newly developed computational method for rigorously evaluating the Hadamard derivative of Laplacian eigenvalues, which plays an important role in studying shape optimization problems. To evaluate the Hadamard derivative, this...

Transportation of measure underlies many powerful, contemporary tools for Bayesian inference, density estimation, and generative modeling. The essential idea is to couple the target probability distribution with a simple, tractable ``reference''...

In my talk I will discuss the notion of local volume for singularities. For the special case of toric singularities this turns out to be closely related to the notion of Mahler volume in convex geometry. This opens a connection between algebraic...
