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 ℤ_N orbifold. We also comment on the subtleties of quantizing the closed superstring in this background.
