Supersymmetric Field Theories on Deformed Space-Time
M. A. Lledó
Field theories on "quantum" or deformed space-time are considered here. The Moyal-Weyl deformation breaks the Lorentz invariance of the theory, but one can still require invariance…

Black Holes and U-duality in Diverse Dimensions
M. A. Lledó
In this paper we review some properties of BPS black holes of supergravities with n=32,16 supersymmetries. The BPS condition, a condition on the eigenvalues of the central charge m…
