Fermionic Schwinger-Keldysh Propagators from AdS/CFT

Abstract

The Herzog and Son prescription for computing real-time Green functions for finite temperature gauge theories from their gravity dual is generalized to fermions. These notes explain how such an extension involves properties of spinors in a curved, complexified space-time.
