Let G be a simple Lie group or Kac-Moody group and P a parabolic subgroup. One of the goals Schubert calculus is to understand the product structure of the cohomology ring H^*(G/P) with respect to its basis of Schubert classes. If G/P is the...

I will try to explain the general background to the subject, and discuss the formulation of the main conjectures of non-commutative Iwasawa theory, on which there has been important recent progress.

I will begin by discussing some recent theoretical and numerical joint work with Liang and Sujatha on the Tate-Shafarevich group of elliptic curves over Q with complex multiplication and rank at least 2. In the latter part of the lecture, I will...

The Yoshida lift is a theta lift that takes a pair of automorphic forms on a definite quaternion algebra to a holomorphic Siegel modular form. We show that a natural refinement of the classical Yoshida lift in fact preserves p-integrality in a...

In these talks we describe our proofs of the Hanna Neumann Conjecture. This conjecture of the late 1950's can be described both as a problem in group theory or as one in graph theory. Our first proof is longer and interprets the problem using...

In this talk a lowest-degree pair of nonconforming finite elements on quadrilaterals and hexahedrons will be introduced for the approximation of the Stokes equations. Also, an equal order pair of nonconforming finite element pair will be introduced...

This is a working seminar on the homotopy theory of moduli spaces

Natural resource problems typically must be modeled using data that is often incomplete, asynchronous and collected at different spatial and temporal scales with differing levels of measurement uncertainty. Both deterministic and stochastic models...
