Extends the geometric formulation to tensor and Chern-Simons couplings.

Applicable to weakly and strongly coupled string theories.

Abstract

This report provides a pedagogical introduction to the description of the general Poincare supergravity/matter/Yang-Mills couplings using methods of Kahler superspace geometry. At a more advanced level this approach is generalized to include tensor field and Chern-Simons couplings in supersymmetry and supergravity, relevant in the context of weakly and strongly coupled string theories.
