Parafermions, Brane Distributions and FRW Hierarchies
P. M. Petropoulos
I review a class of exact string backgrounds, which appear in hierarchies, where the boundary of the target space of an exact sigma model is itself the target space of another exac…
Corfu 05 lectures - part I: Strings on curved backgrounds
Domenico Orlando, P. Marios Petropoulos
In these introductory lectures we summarize some basic facts and techniques about perturbative string theory (sections 1 to 6). These are further developed (sections 7 and 8) for d…
Fluxes, Gaugings and Gaugino Condensates
J. -P. Derendinger, C. Kounnas, P. M. Petropoulos
Based on the correspondence between the N = 1 superstring compactifications with fluxes and the N = 4 gauged supergravities, we study effective N = 1 four-dimensional supergravity…
Gaugino Condensates and Fluxes in N = 1 Effective Superpotentials
Jean-Pierre Derendinger, Costas Kounnas, P. Marios Petropoulos
In the framework of orbifold compactifications of heterotic and type II orientifolds, we study effective N = 1 supergravity potentials arising from fluxes and gaugino condensates.…
