Abstract

We give a simple proof that a particular class of N=2 superstrings are equivalent to the N=1 superstrings. This is achieved by constructing a similarity transformation which transforms the N=2 BRST operators into a direct sum of the BRST operators for the N=1 string and topological sectors.
