Abstract

Generating series of enumerative invariants are often suprisingly connected to period integrals. In this lecture I will explain two ways of establishing relations between Gromov-Witten invariants of elliptic curves and configuration space integrals. One is representation-theoretic based on works of Bloch-Okounkov and Okoukov-Pandharipande, the other is geometric via mirror symmetry. I will mainly focus on the 2nd one, in which regularization of divergent configuration space integrals plays an essential role.

Configurations of boxes
AbstractConfigurations of axis-parallel boxes inare extensively studied in combinatorial geometry. Despite their innocent appearance, there are many old problems involving their structure that are still not well understood. I will talk about a construction, which shows that starting from dimension, configurations of boxes are more complicated than people conjectured.Speaker IntroIstvan Tomon ob...
