Generalised Penrose Limits and PP-Waves
In this paper we construct generalised Penrose limits for the solutions of massive type IIA supergravity. We consider the Freund-Rubin type solution and apply these massive Penrose limits and obtain supersymmetric pp-wave which is standard type IIA background. The results in this paper can be easily generalised for the cases of gauged supergravities.
متن کاملM - theory PP - Waves , Penrose Limits and Supernumerary Supersymmetries
We study supersymmetric pp-waves in M-theory, their dimensional reduction to D0-branes or pp-waves in type IIA, and their T-dualisation to solutions in the type IIB theory. The general class of pp-waves that we consider encompass the Penrose limits of AdS p × S q, but includes also many other examples that can again lead to exactly-solvable massive strings, but which do not arise from Penrose l...
متن کاملPenrose Limits , PP - Waves and Deformed M 2 - branes
Motivated by the recent discussions of the Penrose limit of AdS5 × S5, we examine a more general class of supersymmetric pp-wave solutions of the type IIB theory, with a larger number of non-vanishing structures in the self-dual 5-form. One of the pp-wave solutions can be obtained as a Penrose limit of a D3/D3 intersection. In addition to 16 standard supersymmetries these backgrounds always all...

متن کاملGenerating curvature perturbations with or without MSSM flat directions
We consider instant preheating as the mechanism for generating the curvature perturbation at the end of chaotic inflation. Then we examine if inflation could be driven by a Minimal Supersymmetric Standard Model (MSSM) flat direction or a sneutrino. Our simple mechanism relaxes some serious constraints that appeared in past studies, making inflation driven by a MSSM flat direction or a sneutrino...
