Counting half and quarter BPS states - and their geometric counterparts

Title: Counting half and quarter BPS states - and their geometric counterparts
Abstract: The BPS spectrum of quantum field theories with extended supersymmetry is key to constructing invariants that are reincarnations of geometric or topological invariants. In this talk, we will focus on the complex elliptic genus and its refinements on K3 surfaces and on the non-compact singular spaces that model the singularities which can occur on such K3 surfaces. The results presented here have mostly been obtained in collaboration with Anne Taormina or with Yuhang Hou.
