Titre | APS Eta-invariant, path integrals, and mock modularity |
Résumé | I will show that the Atiyah-Patodi-Singer eta-invariant can be related to the temperature- dependent Witten index of a noncompact theory and will re-derive the APS theorem using scattering theory. I will then motivate how the eta-invariant can be computed using path integral and use this method to compute η-invariant for Cigar. The relation between eta- invariant and Mock modular forms will also be hinted. |
