Non-singular pre-big bang scenarios from all-order $\alpha'$ corrections
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 in the string-loop expansion, but to all orders in the α′ expansion. This allows us to give a simple characterization of...
