This SCAIM lecture is more of a tutorial than a talk. I will present a simple Finite Element Method (FEM) code as a model for the more complex codes in common modern use. Code components include: mesh generation, matrix assembly, a linear solver, and...

We show that on a smooth compact Riemann surface with boundary (M_0, g) the Dirichlet-to-Neumann map of the Schr\"odinger operator \Delta_g + V determines uniquely the potential V. This seemingly analytical problem turns out to have connections with...

In the first half of the talk, I will explain the notion of PT stability, as defined by Bayer. I will also explain how it is related to classical stability conditions on sheaves, and other Bridgeland-type stability conditions. In the second half of...

We wish to understand the boundary between forbidden configurations on 4 rows that yield a quadratic bound and those that have cubic constructions. The result is joint with my supervisor and Attila Sali. The bounds we are concerned with are the...

Studies of the biological effect of ionizing radiation on tissues started almost as soon as the x-ray was discovered by Roentgen in 1895. The need for these studies was also motivated by the early adoption of radiation to treat cancers. Great strides...

Let $M(\alpha)$ denote the Mahler measure of the algebraic number $\alpha$. Dubickas and Smyth constructed a modified version $M_1$ of $M$ having the triangle inequality. $M_1$ is called the metric Mahler measure. We produce an entire parametrized...

Starting from a classical result of Skolem, Mahler and Lech for linear recurrence sequences, we present an algebraic geometric generalization of it. Then we interpret our result from the point of view of dynamics, linking it with the Mordell-Lang...

In recent work of Baas-Dundas-Richter-Rognes, the authors prove that the classifying space of 2-vector bundles, K(Vect) is equivalent to the algebraic K-theory of the connective K-theory spectrum ku. In this talk we will show that K(Vect) is the...

This is an expository talk about the distributive law of algebra and its role in combinatorics, probability, and physics. The main idea is that one can run the distributive law either way, a process sometimes called re-summation. This extraordinarily...
