We study condensation of twisted sector states in the null orbifold geometry.As the singularity is time-dependent, we probe it using D-Instantons. Wepresent evidence that the null-orbifold flows to the $Z_N$ orbifold. We alsocomment on the subtleties of quantizing the closed superstring in thisbackground.Comment: 32 pages, 2 figures, Latex2e, uses JHEP3.cls; v2: references adde

Flow of geometries and instantons on the null orbifold
