Strings in plane-fronted gravitational waves

High Energy Physics - Theory 2009-11-11 v1

Abstract

Brinkmann's plane-fronted gravitational waves with parallel rays --~shortly pp-waves~-- are shown to provide, under suitable conditions, exact string vacua at all orders of the sigma-model perturbation expansion.
