有理回路群的生成元及其几何应用

Generators for Rational Loop Groups and Geometric Applications

Neil Donaldson, Daniel Fox, Oliver Goertsches

摘要:

乌伦贝克证明了一组简单的元素生成一组GL(n,C)中的有理循环,满足U(n)-现实条件。对于一个任意的复约化群,选择一个表示定义了一个合理性的概念,并使我们能够写出一组自然的简单元素。使用这些简单的元素,我们证明生成定理的基本表示的剩余新典型群和大多数对称空间。为了将我们的定理应用于子流形几何,我们还得到了显式的dressing和置换公式。我们引入了一个与G_2/SO(4)相联系的新的子流形几何,并将我们的理论应用于该子流形几何.

英文摘要:

Uhlenbeck proved that a set of simple elements generates the group of rational loops in GL(n,C) that satisfy the U(n)-reality condition. For an arbitrary complex reductive group, a choice of representation defines a notion of rationality and enables us to write down a natural set of simple elements. Using these simple elements we prove generator theorems for the fundamental representations of the remaining neo-classical groups and most of their symmetric spaces. In order to apply our theorems to submanifold geometry we also obtain explicit dressing and permutability formulae. We introduce a new submanifold geometry associated to G_2/SO(4) to which our theory applies.
