From the string vacuum to FLRW or de Sitter via $I^\pm^{'}$ corrections

P. Conzinu, G. Fanizza, M. Gasperini +3

We first make more precise a recent "Hamiltonian" reformulation of the Hohm-Zwiebach approach to the tree-level, $O (d, d)$ -invariant string cosmology equations at all orders in the…

Non-singular pre-big bang scenarios from all-order $I^\pm^{'}$ corrections

M. Gasperini, G. Veneziano

We reformulate in Hamiltonian language the recent proposal by Hohm and Zwiebach of an action yielding the most general $O (d, d)$ -symmetric string cosmology equations, at tree-level…
