Diffusion methods help understand and denoise data sets; when there is additional structure (as is often the case), one can use (and get additional benefit from) a fiber bundle model. This talk reviews diffusion methods to identify low-dimensional...

Mathematical transcendence refers to objects (usually numbers or functions) that do not satisfy any polynomial equation, that is, they are not algebraic. The numbers $\pi$ and $e$ are famous transcendental numbers, and $e^x$ and the Gamma function...

In 2017, Ron Aharoni proposed the following generalization of the Caccetta-Häggkvist conjecture: if G is a simple n-vertex edge-colored graph with n color classes of size at least r, then G contains a rainbow cycle of length at most the ceiling of n...

People interact with each other in social and communication networks, which affect the processes that occur on them. In this talk, I will give an introduction to dynamical proceses on networks. I will focus my discussion on opinion dynamics, and I...

Abelian networks a class of models from statistical physics introduced as models to help understand the complex behavior exhibited by forest fires and avalanches. In this talk we will introduce a few different Abelian networks including activated...

A point-line incidence is a point-line pair such that the point is on the line. The Szemer\'edi-Trotter theorem says the number of point-line incidences for n (distinct) points and lines in R^2 is tightly upperbounded by O(n^{4/3}). We advance the...

UBC DG + MP + PDE Seminar: Marcin Sroka
March 28, 2023
University of British Columbia
I will present some classes of fully nonlinear PDEs on: complex hermitian and Riemannian manifolds which are motivated (respectively) by hypercomplex and quaternionic geometry. In particular, I will formulate the generalization of the conjecture of...

UVictoria Dynamics and Probability Seminar: Emilio Corso

A momentous legacy of twentieth-century mathematics is the realisation that deterministically evolving systems frequently exhibit, when observed for sufficiently extended periods of time, a statistical behaviour akin to the limiting behaviour of...

The classification of 2-dimensional TQFTs was obtained by cutting up surfaces into disks, cylinders, and pairs of pants. In higher dimension, such a decomposition of n-manifolds is not available. We need to cut up manifolds not only along codimension...

Membrane-enclosed fluid objects, or capsules, are everywhere in natural and industrial processes, from red blood cells and circulating tumor cells in the life sciences to encapsulated substances in the pharmaceutical, food and cosmetic industries. A...
