SUMMARY:The geometry of supersymmetric partition functions - Guido Festucc

DESCRIPTION:I will consider supersymmetric field theories on compact manif
 olds M and obtain constraints on the dependence of their partition functio
 ns Z_M on the geometry of M. For N=1 theories with a U(1) R symmetry in fo
 ur dimensions\, M must be a complex manifold with a Hermitian metric. I wi
 ll show how to describe the theory in terms of twisted variables that faci
 litate analyzing the dependence of Z_M on the parameters entering the Lagr
 angian. I will also show that Z_M is "almost" topological:  Z_M is indepen
 dent of the Hermitian metric and depends holomorphically on the complex st
 ructure moduli.
