再论规范理论与几何朗兰兹

More On Gauge Theory And Geometric Langlands

Edward Witten

摘要:

几何朗兰兹对应在几年前被描述为$\N=4$超级杨-米尔斯理论的$S$对偶。这里描述了与这个故事有关的一些其他事项。主要目的是直接解释为什么某种简单类型的$A$ -膜可以是特胡夫特算子作用的本征膜。为了做好准备,我们回顾了一些关于希格斯束和希钦纤维化的事实。我们只考虑最简单的例子,其中许多技术问题可以避免。

英文摘要:

The geometric Langlands correspondence was described some years ago in terms of $S$-duality of $\N=4$ super Yang-Mills theory. Some additional matters relevant to this story are described here. The main goal is to explain directly why an $A$-brane of a certain simple kind can be an eigenbrane for the action of 't Hooft operators. To set the stage, we review some facts about Higgs bundles and the Hitchin fibration. We consider only the simplest examples, in which many technical questions can be avoided.
