AdS/CFT boundary conditions and multi-trace perturbations for fermions
Abstract
Extending the results of a previous paper, we consider boundary conditions for spinor fields and other fields of non-zero spin in the AdS/CFT correspondence. We calculate the RG-flow induced by double trace perturbations dual to bulk spinor fields. For spinors there is a half-unit shift in the central charge in running from the UV to the IR, in accordance with the c-theorem.
