扭转杂种优势几何

Torsional Heterotic Geometries

Katrin Becker, Savdeep Sethi

摘要:

我们构造新的例子扭转杂种优势背景使用对偶与orientifold通量紧化。我们解释如何对偶提供了一个微扰的解决方案,I型/杂合字符串比安奇身份。比安奇恒等式中连接的选择在其结构中起着重要的作用。我们提出了一个更大的景观紧凑扭转几何使用弦对偶的存在。最后,我们提出了一些量子精确度规,对应于NS 5-膜放置在一个椭圆空间。这些度量描述了NS通量如何破坏环面等距。

英文摘要:

We construct new examples of torsional heterotic backgrounds using duality with orientifold flux compactifications. We explain how duality provides a perturbative solution to the type I/heterotic string Bianchi identity. The choice of connection used in the Bianchi identity plays an important role in the construction. We propose the existence of a much larger landscape of compact torsional geometries using string duality. Finally, we present some quantum exact metrics that correspond to NS5-branes placed on an elliptic space. These metrics describe how torus isometries are broken by NS flux.
