Outline of Final Research Achievements |
T-duality is an essential feature of the gravity theory obtained as the low energy effective theory of the string theory. A superspace formulation of type II superstring background with manifest T-duality symmetry is presented in this project. This manifestly T-dual formulation is constructed in a space spanned by two sets of nondegenerate super-Poincare algebra. We introduce Ramond-Ramond charges as a central extension of the algebra. We also present a gauge invariant superstring action with manifest T-dulaity preserving the two-dimensional diffeomorphism invariance and the kappa-symmetry.
