Abstract
The higher-derivative corrections consistent with duality invariance can be completely classified for cosmological, purely time-dependent backgrounds. This result is used to show that there are duality invariant theories featuring string-frame de Sitter vacua as solutions that are non-perturbative in , thus suggesting that classical string theory may realize de Sitter solutions in an unexpected fashion.
