D-BRANE ACTIONS WITH LOCAL KAPPA-SYMMETRY

We formulate world-volume actions that describe the dynamics of Dirich let p-branes in a flat 10d background. The fields in these theories co nsist of the 10d superspace coordinates (X(m), theta) and an abelian w orld-volume gauge held A(mu). The global symmetries are given by the N = 2A or N = 2B super-Poincare group, according to whether p is even o r odd. The local symmetries in the (p + I)-dimensional world volume ar e general coordinate invariance and a fermionic kappa symmetry.
