在弦论中研究真空几何离壳稳定性的一个建议

A proposal for studying off-shell stability of vacuum geometries in string theory

V. Suneeta

摘要:

简要回顾了半经典引力中真空几何的离壳稳定性研究。我们提出了一个研究真空的离壳稳定性的弦论的一个独特的,但有些相关的方法-通过研究他们的稳定性下适当的世界片西格玛模型重整化群(RG)流。RG流下的稳定性在许多情况下是一个数学上的适定性和易处理的问题,正如我们通过例子所示。这样做的好处是,我们可以对弦论中离壳过程的晚期行为和端点做出明确的预测。这是对加拿大理论4,CRM蒙特利尔会议录的贡献。

英文摘要:

We briefly review studies of off-shell stability of vacuum geometries in semiclassical gravity. We propose a study of off-shell stability of vacua in string theory by a distinct, though somewhat related approach -- by studying their stability under suitable world-sheet sigma model renormalization group (RG) flows. Stability under RG flow is a mathematically well-posed and tractable problem in many cases, as we illustrate through examples. The advantage is that we can make definite predictions about late time behaviour and endpoints of off-shell processes in string theory. This is a contribution to the proceedings of Theory Canada 4, CRM Montreal.
