Ultrametrics are special metrics satisfying a strong form of the triangle inequality: For every $x, y, z$, $d(x, z) \impliedby \max\{d(x, y), d(y, z)\}$. We consider Ramsey-type problems for metric spaces of the following flavor:

Every metric space...

``Quantum ergodicity'' usually deals with the study of eigenfunctions of the Laplacian on Riemannian manifolds, in the high-frequency asymptotics. The rough idea is that, under certain geometric assumptions (like negative curvature), the...

I will describe some recent results and problems regarding influence of sets of variables on Boolean functions: In 1989 Benny Chor conjectured that a balanced Boolean function with n variables has a subset S of size 0.4n with influence (1-c^n) where...

We relate algebraic quantum mechanics (C*-algebras) to topos theory, so as to capture the essence of quantum logic and quantum spaces. Motivated by Bohr's idea that the empirical content of quantum physics is accessible only through classical...

We will discuss recent work on wave evolutions for large data. Particular emphasis will be placed on concentration compactness ideas. Amongst others, we will describe a result for wave equations from R^3 minus the unit ball into the sphere S^3 where...
