The -map, Tits Satake subalgebras and the search for inflaton potentials
P. Fré, A. S. Sorin, M. Trigiante
In this paper we address the general problem of including inflationary models exhibiting Starobinsky-like potentials into (symmetric) supergravities. This is done b…
Integrable Scalar Cosmologies II. Can they fit into Gauged Extended Supergavity or be encoded in N=1 superpotentials?
P. Fre, A. S. Sorin, M. Trigiante
The question whether the integrable one-field cosmologies classified in a previous paper by Fre, Sagnotti and Sorin can be embedded as consistent one-field truncations into Extende…
Brane solutions and integrability: a status report
W. Chemissany, P. Fré, J. Rosseel +3
We review the status of the integrability and solvability of the geodesics equations of motion on symmetric coset spaces that appear as sigma models of supergravity theories when r…
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…
Integrable Structures in String Field Theory
L. Bonora, A. S. Sorin
We give a simple proof that the Neumann coefficients of surface states in Witten's SFT satisfy the Hirota equations for dispersionless KP hierarchy. In a similar way we show that t…
On the Super-NLS Equation and its Relation with N=2 Super-KdV within Coset Approach
S. Krivonos, A. Sorin, F. Toppan
A manifestly supersymmetric coset formalism is introduced to describe integrable hierarchies. It is applied to analyze the super-NLS equation. It possesses an symmetry…
