Abstract:
We present a new method for completing higher derivative corrections for
theories that exhibit duality symmetries under reduction. This proposal is
based on the observation that duality symmetry in the reduced theory highly
constrains the form of the unreduced theory. We apply this idea to closed
bosonic string theory and complete the Riemann squared term to simply derive
the known full tree-level effective action to order alpha'.
