Reconstruction of Type II Supergravities via O(d) × O(d) Duality Invariants
Abstract
We reconstruct type II supergravities by using building blocks of O(d) × O(d) invariants.These invariants are obtained by explicitly analyzing O(d) × O(d) transformations of 10 dimensional massless fields. Similar constructions are done by employing double field theory or generalized geometry, but we completed the reconstruction within the framework of the supergravities.
