The unifying superalgebra OSp(1|32)
Eric Bergshoeff, Antoine Van Proeyen
We show how OSp(1|32) gives a unifying framework to describe d=10 type II string theories, d=11 M-theory and d=12 F-theory. The theories are related by different identifications of…

Embedding Branes in Flat Two-time Spaces
L. Andrianopoli, M. Derix, G. W. Gibbons +3
We show how non-near horizon, non-dilatonic -brane theories can be obtained from two embedding constraints in a flat higher dimensional space with 2 time directions. In particul…

Special Kaehler geometry
Antoine Van Proeyen
The geometry that is defined by the scalars in couplings of Einstein-Maxwell theories in N=2 supergravity in 4 dimensions is denoted as special Kaehler geometry. There are several…
