On supergravity in (10,2)
Stephen Hewson
We consider the problem of creating locally supersymmetric theories in signature (10,2). The most natural algebraic starting point is the F-algebra, which is the de Sitter-type (10…
Threebranes in twelve dimensions
Stephen F. Hewson
In this note we discuss the theory of super-threebranes in a spacetime of signature (10,2). Upon reduction, the threebrane provides us with the classical representations of the M-2…
An approach to F-theory
S. F. Hewson
We consider BPS configurations in theories with two timelike directions from the perspective of the supersymmetry algebra. We show that whereas a BPS state in a theory with one tim…
Potentials and T-duality
S. F. Hewson, N. D. Lambert
We discuss the application of T-duality to massive supersymmetric sigma models. In particular (1,1) supersymmetric models with off-shell central charges reveal an interesting struc…
Generalised supersymmetry and p-brane actions
S. Hewson
We investigate the most general N=1 graded extension of the Poincare algebra, and find the corresponding supersymmetry transformations and the associated superspaces. We find that…
The twelve dimensional super (2+2)-brane
S. F. Hewson, M. J. Perry
We discuss supersymmetry in twelve dimensions and present a covariant supersymmetric action for a brane with worldsheet signature (2,2), called a super (2+2)-brane, propagating in…
