We consider a region in the complex plane enclosed by a deltoid curve inscribed in the unit circle, and define a family of polynomials that satisfy the same recurrence relation as the Faber polynomials for this region. We use this family of...

This work investigates the integration of machine scheduling and personnel allocation problems. In machine scheduling, the goal is to find the optimal assignment of jobs to machines within a given time horizon, considering processing times and...

Much of the recent rigorous progress on the classical Ising model was driven by new detailed understanding of its stochastic geometric representations. Motivated by the problem of establishing exponential decay of truncated correlations of the...

Given two manifolds M and N, one can ask whether it is possible to cut M up into pieces and reassemble them to obtain N. This “cut-and-paste” (SK) relation fits into the framework of scissors congruence K-theory, which is an extension of higher...

Site percolation models are probability distributions of 2-colorings of the vertices of locally finite infinite graphs. Historically, they have been studied on graphs exhibiting symmetries such as (quasi)-transitivity. In joint work with Alexander...

Choleraremains a significant public health threat in many parts of the world, withdiffering levels of compliance to intervention strategies and undocumentedcases contributing to reservoir contamination with Vibrio cholerae at varyingrates alongside...

The UBC Applied Mathematics Meeting is a one day conference dedicated to the newly created SIAM Student Chapter at UBC, Vancouver, Canada. This event aims to bring together mathematicians, industry researchers, and students to exchange ideas, present...

In this talk I will present a series of works derived from the framework of physics inspired graph neural networks (GNN). The central premise is a GNN can be seen as the discretisation of a learnable dynamical system over a graph, this allows to...

Random walks or diffusions with Dirichlet boundary condition (killing at the boundary) admit a Perron-Frobenius eigenfunction (the unique positive normalized eigenfunction when the domain is bounded). Starting with gambler's ruin problems, we discuss...

The first regularity results for maps optimizing an open class of cost were proved by Ma-Trudinger-Wang (2005) using a key inequality which they introduced (based on a classical strategy of Pogorelov). Away from the boundary, this inequality controls...
