Evolution of Gravitationally Unstable de Sitter Compactifications

High Energy Physics - Theory 2009-11-11 v2

Abstract

We study the time evolution of unstable dSpdS_p \times SqS^q configurations with flux in theories of gravity with a cosmological constant. For certain values of the flux, we identify a stable configuration to which these unstable solutions flow. For other values of the flux the sphere wants to decompactify, regardless of the sign of the initial perturbation.
