Recent work has proposed a method for imposing T-duality on the metric, *B*-field, and dilaton of the classical effective action of string theory without using Kaluza-Klein reduction. Specifically, the *D*-dimensional effective action should be invariant under global *O(D,D)* transformations, provided that the partial derivatives along the *\beta*-parameters of the non-geometrical...
