“Prepotentials” in a superspace formulation of supergravity

, 1978
Certain of the superspace equations in our previous work are utilized to express the superconnection and vielbein in terms of a much smaller set of fields, the "prepotentials", which include chiral coordinates of curved ...

Superstrings and geometry of superspace

, 1986
These lectures present some recent developments in the sigma-model approach to the Green-Schwarzsuperstring. Among the topics included are: (1) interpretation of the free superstring as a flat superspace sigma-model; (2) propagation of the superstring in

Tutte polynomials in superspace [PDF]

We associate a quotient of superspace to any hyperplane arrangement by considering the differential closure of an ideal generated by powers of certain homogeneous linear forms. This quotient is a superspace analogue of the external zonotopal algebra, and
