Let G be a finite group. A G-gerbe over a space X may be intuitively thought of as a fiber bundle over X with fibers being the classifying space (stack) BG. In particular BG itself is the G-gerbe over a point. A more interesting class of examples...

In his influential works, A. Okounkov showed how to associate a convex body to a very ample G-line bundle L on a projective G-variety X such that it projects to the moment polytope of X and the push-forward of the Lebesgue measure on it gives the...

Abstract: Fully irreducible outer automorphisms of a free group are analogous to loxodromic isometries of hyperbolic space, or to pseudo-Anosov elements of the mapping class group of a surface. We develop methods for constructing customized fully...

In this talk I'll (a) provide an overview of the history of probability and statistics, shedding some light on a 19th- and 20th-century dispute between two probabilistic schools (frequentist and Bayesian), (b) explain why a fusion between the two...

It is expected that a general K3 surface does not admit self rational maps of degree > 1. I'll give a proof of this conjecture for K3 surfaces of genus at least 4.

We seek to build a computational model for the simplified Mammalian Cochlea with the standard coupled fluid-plate equations as our base. Physiological data shows a clear wave nature in the response of the basilar membrane to stimulus. We seek to...
