Tits-Satake projections of homogeneous special geometries
Pietro Fre', Floriana Gargiulo, Jan Rosseel +3
We organize the homogeneous special geometries, describing as well the couplings of D=6, 5, 4 and 3 supergravities with 8 supercharges, in a small number of universality classes. T…
Cosmic Billiards with Painted Walls in Non-Maximal Supergravities: a worked out example
Pietro Fre', Floriana Gargiulo, Ksenya Rulik
The derivation of smooth cosmic billiard solutions through the compensator method is extended to non maximal supergravities. A new key feature is the non-maximal split nature of th…
The general pattern of Kac Moody extensions in supergravity and the issue of cosmic billiards
Pietro Fre', Floriana Gargiulo, Ksenya Rulik +1
In this paper we study the systematics of the affine extension of supergravity duality algebras when we step down from D=4 to D=2. For all D=4 supergravities (with N >= 3) there is…
Exact solutions for Bianchi type cosmological metrics, Weyl orbits of E_{8(8)} subalgebras and p--branes
P. Fré, K. Rulik, M. Trigiante
In this paper we pursue further a programme initiated in a previous work and aimed at the construction, classification and property investigation of time dependent solutions of sup…
Cosmological backgrounds of superstring theory and Solvable Algebras: Oxidation and Branes
P. Fre', V. Gili, F. Gargiulo +3
We develop a systematic algorithm to construct, classify and study exact solutions of type II A/B supergravity which are time--dependent and homogeneous and hence represent candida…
On the effective lagrangian in spinor electrodynamics with added violation of Lorentz and CPT symmetries
Yu. A. Sitenko, K. Yu. Rulik
We consider quantum electrodynamics with additional coupling of spinor fields to the space-time independent axial vector violating both Lorentz and CPT symmetries. The Fock-Schwing…
