Abstract

We present an N = 2 world‐sheet superspace description of D‐branes on bihermitian or generalized Kähler manifolds. To accomplish this, D‐branes are considered as boundary conditions for a nonlinear σ‐model in what we call N = 2 boundary superspace. In this note the general formalism for such an approach is presented and the resulting classification sketched. This includes some remarks regarding target spaces whose parameterization includes semi‐chiral superfields which have not appeared in the literature yet. In an accompanying note we turn to some examples and applications of the general setup presented here.
