D膜瞬子与矩阵模型

D-brane instantons and matrix models

Iñaki García-Etxebarria

摘要:

指出在某些情况下,利用Dijkgraaf-Vafa方法中的矩阵模型技术微扰计算D膜瞬子效应是可能的。这提供了hep-th/0311181中结果的弦瞬子方面的解释。我们在一些简单的场景中检查这个提议。我们指出一些有趣的后果,这一观察,如事实上,它提供了一个微扰的方式计算弦多瞬子效应。它也提供了一个进一步的解释D-膜瞬子作为剩余瞬子的higgsed超群。

英文摘要:

We point out that in some situations it is possible to use matrix model techniques a la Dijkgraaf-Vafa to perturbatively compute D-brane instanton effects. This provides an explanation in terms of stringy instantons of the results in hep-th/0311181. We check this proposal in some simple scenarios. We point out some interesting consequences of this observation, such as the fact that it gives a perturbative way of computing stringy multi-instanton effects. It also provides a further interpretation of D-brane instantons as residual instantons of higgsed supergroups.
