A result of Jan Nekovář says that the Galois action on p-adic intersection cohomology of Hilbert modular varieties with coefficients in automorphic local systems is semisimple. We will explain a new proof of this result for the non-CM part of the...

We use the min-max construction to find closed hypersurfaces which are stationary with respect to anisotropic elliptic integrands in any closed n-dimensional manifold . These surfaces are regular outside a closed set of zero n-3 dimension. The...

Thurston gave an explicit construction of pseudo-Anosov elements 
in the mapping class group of a compact surface, using Dehn twists in 
pairs of filling multicurves.  We show that the probability that a random 
walk of length $n$ on the mapping class...
