“…It would also be interesting to explore whether our results hold for higher orders in the derivative expansion. Building these actions seems a quite difficult challenge, albeit substantial progress has been achieved recently [29,30].…”

We examine a two parameter family of gravitational actions which contains higher-derivative terms. These are such that the entire action is invariant under corrected T-duality rules, which we derive explicitly. Generically this action does not describe low energy string backgrounds except for isolated choices for the parameters.Nevertheless, we demonstrate that in this theory the entropy and the temperature of generic non-extremal black hole solutions are T-duality invariant. This further supports the idea put forward in our previous work that T-duality might provide physical equivalences beyond the realm of string theory.Dedicated to the memory of Stephen Hawking, one year after his passing

Recently, it has been shown that the gauge invariance requires the minimum number of independent couplings for B-field, metric and dilaton at order α ′2 to be 60. In this paper we fix the corresponding 60 parameters in string theory by requiring the couplings to be invariant under the global T-duality transformations. The Riemann cubed terms are exactly the same as the couplings that have been found by the S-matrix calculations.

“…This program, however, has not yet been developed to the point that it can deal with the set of all α 1 corrections for bosonic or heterotic string theory. (See, however, the recent proposal for heterotic string theory [22]. )…”

Duality invariant cosmology to all orders in α′

While the classification of α 1 corrections of string inspired effective theories remains an unsolved problem, we show how to classify duality invariant α 1 corrections for purely time-dependent (cosmological) backgrounds. We determine the most general duality invariant theory to all orders in α 1 for the metric, b-field, and dilaton. The resulting Friedmann equations are studied when the spatial metric is a timedependent scale factor times the Euclidean metric and the b-field vanishes. These equations can be integrated perturbatively to any order in α 1 . We construct nonperturbative solutions and display duality invariant theories featuring string-frame de Sitter vacua.
