Supergravity and M-Theory†
Supergravity provides the effective field theories for string compactifications. The deformation of the maximal supergravities by non-abelian gauge interactions is only possible for a restricted class of charges. Generically these ‘gaugings’ involve a hierarchy of p-form fields which belong to specific representations of the duality group. The group-theoretical structure of this p-form hierarch...
متن کاملSupergravity, M theory and Cosmology
We discuss some recent attempts to reconcile cosmology with supergravity and M/string theory. First of all, we point out that in extended supergravities the scalar masses are quantized in terms of the cosmological constant in de Sitter vacua: the eigenvalues of the Casimir operator 3m/Λ take integer values. For the current value of the cosmological constant extended supergravities predict ultra...
متن کاملM–theory geometrical transitions from gauged supergravity
We study the supergravity duals of supersymmetric theories arising in the world–volume of D6 branes wrapping holomorphic two–cycles and special Lagrangian three–cycles within the framework of eight dimensional gauged supergravity. When uplifted to 11d, our solutions represent M–theory on the background of, respectively, the small resolution of the conifold and a manifold with G2 holonomy. We fu...

متن کاملDlcq-m(atrix) Description of String Theory, and Supergravity
We discuss the connection between Matrix string theory and the DLCQ of string theory. Using this connection we describe the sense in which perturbative string amplitudes are reproduced in the Matrix string theory. Using recent realization of the connection between SYM and Supergravity, we suggest how to describe Matrix theory with non-flat backgrounds.
