Spontaneously broken supergravity: Old and new facts
R. D'Auria, S. Ferrara, M. Trigiante
We report on some recent investigations of the structure of the four dimensional gauged supergravity Lagrangian which emerges from flux and Scherk-Schwarz compactifications in high…
Curvatures and potential of M-theory in D=4 with fluxes and twist
R. D'Auria, S. Ferrara, M. Trigiante
We give the curvatures of the free differential algebra (FDA) of M--theory compactified to D=4 on a twisted seven--torus with the 4--form flux switched on. Two formulations are giv…
Gauging the Heisenberg algebra of special quaternionic manifolds
R. D'Auria, S. Ferrara, M. Trigiante +1
We show that in N=2 supergravity, with a special quaternionic manifold of (quaternionic) dimension h_1+1 and in the presence of h_2 vector multiplets, a h_2+1 dimensional abelian a…
Gauged extended supergravity without cosmological constant: no-scale structure and supersymmetry breaking
L. Andrianopoli, R. D'Auria, S. Ferrara +1
We consider the interplay of duality symmetries and gauged isometries of supergravity models giving N-extended, spontaneously broken supergravity with a no-scale structure. Some ex…
