 Marius Junge (Illinois Math)Non-locality from a math perspectiveAbstract: We discuss several ways to measure how  a bipartite  state can be used to perform non-local experiments. Traditionally, the entropy of entanglement is considered as such a measure. A more recent approach consists on constructing Bell-type inequalities as a witness of non-locality. The mathematical results will show that certain states are non-local in a very robust sense. If time allows we will describe recent results of Palazuelos, formerly a postdoc at UIUC, on superactivation of non-locality.

 Valentino Magnani (University of Pisa, Italy)On the sub-Riemannian measure of submanifoldsAbstract: We present an explicit formula for the sub-Riemannian measure of a submanifold, embedded in a fixed stratified group. We show that in many cases this measure is equivalent to the Hausdorff measure of the submanifold with respect to the sub-Riemannian distance of the group. We discuss the important class of transversal submanifolds, for which the equivalence between Hausdorff measure and sub-Riemannian measure holds. This result has been recently obtained in collaboration with Jeremy Tyson and Davide Vittone. Some open questions will be addressed.
