A note on T-folds and T 3 fibrations

Blog Article

Abstract We study stringy modifications of T 3-fibered manifolds, where the fiber undergoes a monodromy in the T-duality group.We determine the fibration data defining such T-folds from a geometric Pillows model, by using a map between the duality group and the group of large diffeomorphisms of a four-torus.We describe the monodromies induced around duality defects where such fibrations degenerate and we argue that local solutions receive Horse Cooler Rugs corrections from the winding sector, dual to the symmetry-breaking modes that correct semi-flat metrics.
