On full-fledged supergravity cosmologies and their Weyl group asymptotics
Pietro Fré, Jan Rosseel
We consider a class of cosmological solutions of d=4, N=2 supergravity theories coupled to vector multiplets. The solutions result from performing a compactification to three dimen…
Pure Spinors for General Backgrounds
Pietro Fre', Pietro Antonio Grassi
We show the equivalence of the different types of pure spinor constraints geometrically derived from the Free Differential Algebras of N=2 d=10 supergravities. Firstly, we compute…
Free Differential Algebras, Rheonomy, and Pure Spinors
Pietro Fré, Pietro Antonio Grassi
We report on progresses on the derivation of pure spinor constraints, BRST algebra and BRST invariant sigma models a la pure spinors from the algebraic structure of the FDA underly…
The arrow of time and the Weyl group: all supergravity billiards are integrable
Pietro Fré, Alexander S. Sorin
In this paper we show that all supergravity billiards corresponding to sigma-models on any U/H non compact-symmetric space and obtained by compactifying supergravity to D=3 are ful…
Constrained Supermanifolds for AdS M-Theory Backgrounds
Pietro Fré, Pietro Antonio Grassi
A long standing problem is the supergauge completion of AdS_4 x (G/H)_7 or AdS_5 x (G/H)_5 backgrounds which preserve less then maximal supersymmetry. In parallel with the supersol…
