Cubic fourfolds have been classically studied up to birational equivalence, with a view toward the rationality problem. The Fano variety of lines F(X) on a cubic fourfold X is a hyperkähler manifold, and the rationality of X is conjecturally captured...

I will discuss several recent results on the Turán density of long cycle-like hypergraphs. These results (due to Kamčev–Letzter–Pokrovskiy, Balogh–Luo, and myself) all follow a similar framework, and I will outline a general strategy to prove Turán...

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...

In this talk, I'll share my experience transitioning from a sub-par academic background in pure math to a career in Applied Statistics. I'll discuss the internships I've had and how they provided a foundation for my current work. I'll walk through...

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...

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...

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...

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...
