Flux, Supersymmetry and M theory on 7-manifolds
B. S. Acharya, B. Spence
Various aspects of low energy M theory compactified to four dimensions are considered. If the supersymmetry parameter is parallel in the unwarped metric, then supersymmetry require…

Topological Born-Infeld Actions and D-Branes
B. Spence
We propose that the effective field theories of certain wrapped D-branes are given by topological actions based on Born-Infeld theory. In particular, we present a Born-Infeld versi…

The phase space of the Wess-Zumino-Witten model
G. Papadopoulos, B. Spence
We prove that the covariant and Hamiltonian phase spaces of the Wess-Zumino-Witten model on the cylinder are diffeomorphic and we derive the Poisson brackets of the theory.
