Abstract:
An O(d,d)O(d,d) symmetry of the manifold of string vacua that do not depend on dd (out of DD) space-time coordinates has been recently identified. Here we write down, for d=D1d=D-1, the low energy equations of motion and their general solution in a manifestly O(d,d)O(d,d)-invariant form, pointing out an amusing similarity with the renormalization group framework. Previously considered cosmological and black hole solutions are recovered as particular examples.
