作为超重力背景的非几何通量

Non-geometric fluxes as supergravity backgrounds

Fernando Marchesano, Waldemar Schulgin

摘要:

我们考虑D=4的弦论真空的例子,尽管它整体上是非几何的,但允许用D=10的超引力背景进行局部描述。我们分析了这样的背景,发现超对称旋量沿内部流形非平凡地变化,再现了Frey和Grana发现的插值超引力解。最后,我们提出了一个简单的,本地的表达非几何通量的紧化的内部旋量。

英文摘要:

We consider examples of D=4 string theory vacua which, although globally non-geometric, admit a local description in terms of D=10 supergravity backgrounds. We analyze such backgrounds and find that the supersymmetry spinors vary non-trivially along the internal manifold, reproducing the interpolating supergravity solutions found by Frey and Grana. Finally, we propose a simple, local expression for non-geometric fluxes in terms of the internal spinors of the compactification.
