✦ Synopsis

Abstract

We present a manifestly supersymmetric description of A and B branes on Kähler manifolds using a completely local N = 2 superspace formulation of the world‐sheet nonlinear σ‐model in the presence of a boundary. In particular, we show that an N = 2 superspace description of type A boundaries is possible. This leads to a concrete realization of the still poorly understood coisotropic A branes. We also discuss briefly how the superspace description of a B brane provides an efficient way to compute higher loop β‐functions. In particular, we sketch how one obtains the fourth order derivative correction to the Born‐Infeld action by using a β‐function method.

## Abstract We discuss orientifold projections on superspace effective actions for hypermultiplets. We present a simple and new mechanism that allows one to find the Kähler potential and complex structure for the __N__ = 1 theory directly in terms of the parent __N__ = 2 theory. As an application,

## Abstract We review the analysis of the tachyon and RR scalar spacetime field configurations sourced by the (__m__, __n__) ZZ D‐branes in type 0 theories. We focus on three approaches: the mini‐superspace approximation, a motivated ansatz to go beyond the semi‐classical approximation and finally
