李理论与几何中的复伴随轨道

Complex adjoint orbits in Lie theory and geometry

Peter Crooks

摘要:

这篇文章介绍了复杂半单群的伴随轨道,主要是在代数几何和李理论的背景下,并强调了半单和幂零轨道的性质。它的目的是建立一个基础,更专门的设置,其中伴随轨道功能突出(例如。超凯勒几何,朗道-金兹伯格模型,辛奇点理论)。还包括一些论点和意见,据作者所知,尚未出现在研究文献。

英文摘要:

This expository article is an introduction to the adjoint orbits of complex semisimple groups, primarily in the algebro-geometric and Lie-theoretic contexts, and with a pronounced emphasis on the properties of semisimple and nilpotent orbits. It is intended to build a foundation for more specialized settings in which adjoint orbits feature prominently (ex. hyperkähler geometry, Landau-Ginzburg models, and the theory of symplectic singularities). Also included are a few arguments and observations that, to the author's knowledge, have not yet appeared in the research literature.
