具有$B$ -域的Calabi-Yau流形

Calabi-Yau manifolds with $B$-fields

Frederik Witt

摘要:

在最近的工作N。希钦介绍了“广义几何”的概念。广义结构的关键特征是它们可以被双同态和2-形式作用,即所谓的$B$ -域。在这个讲座中,我们给出了一个基本的介绍,并解释了一些基本的想法。此外,我们讨论了一些例子,广义几何开始从通常的概念的卡-丘流形,以及应用弦理论。

英文摘要:

In recent work N. Hitchin introduced the concept of "generalised geometry". The key feature of generalised structures is that that they can be acted on by both diffeomorphisms and 2-forms, the so-called $B$-fields. In this lecture, we give a basic introduction and explain some of the fundamental ideas. Further, we discuss some examples of generalised geometries starting from the usual notion of a Calabi-Yau manifold, as well as applications to string theory.
