Abstract: We will discuss Brock's theorem on volumes of hyperbolic mapping tori in this PA seminar. Brock's theorem relates the volume of a hyperbolic mapping torus to the Weil-Petersson translation distance of the associated holonomy map.  After a very short introduction, I will introduce the main ingredients and then sketch the proof of the theorem.

Valuation theory plays a major part in the interaction between number theory and logic. In this seminar, a variety of topics from valuation theory, and in particular connections to model theory, will be discussed. There will be a strong emphasis on results involving the definability of valuations.

Abstract:
Given a complete theory T of henselian valued fields of characteristic 0, we  axiomatize the class of existentially closed differential expansions of models of T. Let us denote this axiomatization by T_\delta^*. Then we examine which model-theoretic properties transfer from T to T_\delta^* such as the existence of a dimension function on definable sets, or the existence of a code for definable sets (elimination of imaginaries). The main technical tool is a cell decomposition theorem for models of T and a description of definable functions (and more generally correspondences). (This is the analog in this setting of a result of P. Simon and E. Walsberg for dp-minimal, non strongly minimal fields of characteristic 0). Then we illustrate why this set-up is convenient to look at dense pairs of models of T. This is joint work with Nicolas Guzy and Pablo Cubidès.

This mini course is an introduction to the theory, computation, and applications of Picard-Fuchs differential equations.  The main prerequisite is knowledge of basic complex algebraic geometry at the introductory graduate level.  We will develop a thorough understanding, from several different theoretical perspectives, of some of the key examples in the mathematics and physics literature.  This course should be of interest to geometers, model theorists, and physicists alike.

After about five years in academia, with NSF grants, a bunch of publications, and a couple of awards for my articles, I realized that the academic life didn’t work for me personally or intellectually. So, I reinvented myself as an industrial mathematician.

I am glad I did I made the transition. I have worked on some very interesting projects in a wide range of fields. I have the enjoyed seeing my work having practical impact. And, I have had great colleagues and get to mentor some very some intelligent and motivated junior staff.

In this discussion, I will share some of my industry experiences, lessons learned about the industrial mindset, and some of the current math problems being tackled today by industry.

Abstract: We present new results on the complexity of the classification problem of countable structures and their computational complexity. We show that the elementary bi-embeddability relation on the class of graphs is analytic complete under Borel reducibility by giving a reduction from the bi-embeddability relation on graphs. We then compare the degree spectra with respect to these equivalence relations. The degree spectrum of a countable structure with respect to an equivalence relation E is the set of Turing degrees of structures E-equivalent to it. We show that the degree spectra of structures with respect to bi-embeddability and elementary bi-embeddability are related: Every bi-embeddability spectrum of a graph is the set of jumps of Turing degrees in the elementary bi-embeddability spectrum of a graph.
