A note on T-folds and T3 fibrations

Ismail Achmed-Zade, Mark J. D. Hamilton, Dieter Lust, Stefano Massai

摘要:

我们研究了$T^3$纤维流形的弦变形,其中纤维在T-对偶群中经历单值性。我们确定的纤维化数据定义这样的T-倍的几何模型,通过使用之间的映射的对偶群和组的大的四环面的超同构。我们描述的monodromies诱导周围的对偶缺陷,这种纤维化退化,我们认为,当地的解决方案接收校正绕组部门,双到正确的半平坦度量的破坏模式。

英文摘要:

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 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 corrections from the winding sector, dual to the symmetry-breaking modes that correct semi-flat metrics.
