A non-linear generalization of the Kakutani Equidistribution problem

February 12, 2026

ESB 4133

Take the unit interval [0,1] and a number, b, between 0 and 1. At each step, split every interval of maximal length into two pieces in proportion b: (1-b). This recursive scheme is known as the Kakutani splitting procedure and in 1976, Kakutani showed that the sequence of partitions becomes... Read more

Mathematical Perspectives on Tumour–Immune Dynamics in a Changing Landscape (PIMS network-wide colloquium)

February 12, 2026

Zoom. Register here: https://ubc.zoom.us/meeting/register/OoGJFra5SMiLY8pSQJqhJw#/registration

Immune cell infiltration in solid tumours was once regarded as clear evidence of the body’s attempt to eradicate a malignant threat. It is, however, now well established that tumours can co-opt immune cells, reprogramming them from tumour-suppressive defenders into tumour-promoting collaborators... Read more

Optimal matchings of randomly perturbed lattices

February 11, 2026

Consider a point process in Euclidean space obtained by perturbing the integer lattice with IID Gaussians. Our goal is to match the perturbed points with the points of the lattice in an invariant way and such that the typical matching distance is as small as possible (or nearly so). One obvious...

Math-Bio: A minimal model of pediatric sickle cell pain

February 11, 2026

LSK 306 (IAM Lounge)

Sickle cell pain presents in acute episodes in pediatric patients, as opposed to the chronic pain observed in adults. The episodic nature of pain events in pediatric patients necessitates a distinct approach from what has been used to mathematically model pain severity levels in adults.... Read more

Exponential PDEs in high dimensions

February 10, 2026

PIMS Library - ESB 4133

I will report on recent progress in the study of a quasilinear equation involving the n-Laplacian and an exponential nonlinearity in R^n . In particular quantization issues for blow-up masses in the non-compact situation will be discussed and their relationship with Harnack inequalities of sup... Read more

An explicit construction of a rank-2 vector bundle on projective 3-space

February 10, 2026

Atiyah and Rees proved that the Chern classes and a mod 2 invariant, named the alpha invariant, classifies all rank 2 topological vector bundles on P3. They also showed that a construction by Horrocks provides algebraic representatives for all topological rank 2 bundles. However, Horrocks’... Read more

The tableaux algebra, with applications to geometry and crystals

February 9, 2026

Tableaux are fundamental objects in representation theory and combinatorics, and variations of the Schensted algorithm have endowed them with rich algebraic structures. In this talk I will discuss a naive monoid structure on the set of semistandard Young tableaux that does not arise as an... Read more

On the Iwasawa theory of digraphs

February 6, 2026

ESB 2012 and Zoom

Classical Iwasawa theory studies the variation of arithmetic invariants, such as ideal class groups, along infinite towers of number field extensions. Over the years, these ideas have been extended to a wide range of arithmetic objects, including elliptic curves, modular forms, and abelian... Read more
