Central predictions of arithmetic quantum chaos such as the Quantum Unique Ergodicity conjecture and the sup-norm problem ask about the mass distribution of automorphic forms, most classically in terms of their weight or Laplace eigenvalue (for...

I will show that any Schubert or Richardson variety R in a flag manifold G/P is equivariantly rigid and convex. Equivariantly rigid means that R is uniquely determined by its equivariant cohomology class, and convex means that R contains any torus...

We describe three constructions of spherical roots of spherical varieties via embddings, Borel orbits, and harmonic analysis, and give a hint for why they yield the same results. Then we describe more recent extensions of this theory to arbitrary G...

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...

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...
