Past Events

In the first part of the talk, I will explain why we may need to go beyond the standard framework of transition state theory (TST) to describe activated processes and reactive events, and I will present another framework, termed transition path...

In the first of a two lecture series (to be completed by Dave Anderson immediately following), we present a new geometric interpretation of equivariant cohomology in which one replaces a smooth, complex $G$-variety $X$ by its associated arc space $J_...

Let G be an algebraic group acting on a smooth complex variety X. In joint work with Alan Stapledon, we present a new perspective on the G-equivariant cohomology of X, which replaces the action of G on X with the induced action of the respective arc...

While univariate polynomial interpolation has been a basic tool of scientific computing for hundreds of years, multivariate polynomial interpolation is much less understood. Already the question from which polynomial space to choose an interpolant to...

In stable homotopy theory the thick subcategory theorem of Hopkins and Smith classifies thick subcategories of the triangulated category of p-torsion finite spectra. Unstably Bousfield classified nullity classes of p-torsion finite suspensions. We...

Start a totally asymmetric simple exclusion process with a second class particle at 0, particles to its left and holes to its right. If Xt is the location at time t of the second class particle, then Xt / t converges a.s. to a uniform [-1,1] random...

I will discuss the scattering problem of mass-critical generalized KdV equation. We will see if the scattering of gKdV fails, then a minimal mass blow-up solution exist on the condition that scattering of mass-critical 1D NLS is true. We use...

Mathematical and computational models are becoming more prominent in biological and bioinformatics research. However, the designing, programming, testing and even utilization of computer models has not yet found the acceptance it deserves within the...

Kostant's remarkable formula (which I will recall) generalizes to smooth Schubert varieties in the flag variety G/B of an algebraic group G. On the other hand, Sara Billey noticed that rationally smooth Schubert varieties in G/B give an analogous...
