Flow of Geometries and Instantons on the Null Orbifold

High Energy Physics - Theory 2009-11-11 v2

Abstract

We study condensation of twisted sector states in the null orbifold geometry. As the singularity is time-dependent, we probe it using D-Instantons. We present evidence that the null-orbifold flows to the ZNZ_N orbifold. We also comment on the subtleties of quantizing the closed superstring in this background.
