Abstract
We compute the BRST cohomology of the holomorphic part of the N = 2 string at arbitrary ghost and picture number. We confirm the expectation that the relative cohomology at non-zero momentum consists of a single massless state in each picture. The absolute cohomology is obtained by an independent method based on homological algebra. For vanishing momentum, the relative and absolute cohomologies both display a picture dependence - a phenomenon discovered recently also in the relative Ramond sector of N = 1 strings by Berkovits and Zwiebach [1].
