D-Brane Actions, Intrinsic Geometry and Duality
M. Abou Zeid
We discuss an alternative form of the supersymmetric D--brane action which is quadratic in derivatives of and linear in . This action involves an auxiliary worldvolu…
Conformal Invariance and Duality in Self-Dual Gravity and (2,1) Heterotic String Theory
M. Abou Zeid, C. M. Hull
A system of gravity coupled to a 2-form gauge field, a dilaton and Yang-Mills fields in dimensions arises from the (2,1) sigma model or string. The field equations imply that…
The Gauged (2,1) Heterotic Sigma-Model
M. Abou Zeid, C. M. Hull
The geometry of (2,1) supersymmetric sigma-models with isometry symmetries is discussed. The gauging of such symmetries in superspace is then studied. We find that the coupling to…
Intrinsic Geometry of D-Branes
M. Abou Zeid, C. M. Hull
We obtain forms of Born-Infeld and D-brane actions that are quadratic in derivatives of and linear in by introducing an auxiliary `metric' which has both symmetric and…
