The Geometry of Sigma-Models with Twisted Supersymmetry
Mohab Abou Zeid, Christopher M. Hull
We investigate the relation between supersymmetry and geometry for two dimensional sigma models with target spaces of arbitrary signature, and Lorentzian or Euclidean world-sheets.…
Geometric Actions for D-Branes and M-Branes
M. Abou Zeid, C. M. Hull
New forms of Born-Infeld, D-brane and M theory five-brane actions are found which are quadratic in the abelian field strength. The gauge fields couple both to a background or induc…
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…
Geometry, Isometries and Gauging of (2,1) Heterotic Sigma-Models
M. Abou Zeid, C. M. Hull
The geometry of (2,1) supersymmetric sigma-models is reviewed and the conditions under which they have isometry symmetries are analysed. Certain potentials are constructed that pla…
