Geometry of N=1 Yang-Mills theory in curved superspace

Generalises the formalism of Ogievetsky and Sokatchev (1980) to describe the geometry of N=1 supersymmetric Yang-Mills theory (coupled in general to supergravity). This generalisation seems to be analogous to the Kaluza theory. The author's presentation uses recent developments in geometry of supergravity and exhibits some similarity with the construction of Atiyah and Ward (1977).
