| Titre | Partition function on Hopf surfaces and supersymmetric Casimir energy |
| Résumé | I will discuss the partition function of 4d N=1 theories on Hopf surfaces. These are diffeomorphic to S^1 x S^3 and the partition function provides a path integral realization of the supersymmetric index. Its large S^1 limit exhibits a universal behaviour associated to the existence of a non-vanishing Casimir energy. I will argue that this notion of vacuum energy is intrinsic (scheme-independent) and can be computed as the vev of the Hamiltonian in the free limit of the theory. |
