Generalised Penrose Limits and PP-Waves

arXiv:hep-th/0307088 · doi:10.1016/j.physletb.2004.01.025

Abstract

In this paper we construct generalised Penrose limits for the solutions of massive type IIA supergravity. We consider a Freund-Rubin type solution and apply these {\it massive} Penrose limits and obtain supersymmetric pp-wave which is a standard type IIA background. We point out that results in this paper are easily generalised for the cases of gauged supergravities.
