„Closed characteristics on the boundary of convex polytopes“
Frau Pazit Haim Kislev, Tel Aviv University, Israel

We introduce a simplification to the problem of finding a closed characteristic with minimal action on the boundary of a convex polytope in $R^2n$, which yields a combinatorial formula for the EHZ capacity. As an application, we show that the EHZ capacity of a general convex body is sub-additive with respect to hyperplane cuts, and we bound the systolic ratio for simplices in $R^4$.
