实几何不变量理论

Real geometric invariant theory

Christoph Böhm, Ramiro A. Lafuente

摘要:

对于实约化李群的线性作用,我们证明了关于闭轨道的Kempf-Ness定理和零锥的Kirwan-Ness分层定理。由于我们完全独立的证明主要集中在几何和分析方法上,基本上避免了任何深刻的代数结果,因此它也适用于非有理线性作用。

英文摘要:

For linear actions of real reductive Lie groups we prove the Kempf-Ness Theorem about closed orbits and the Kirwan-Ness Stratification Theorem of the null cone. Since our completely self-contained proof focuses strongly on geometric and analytic methods, essentially avoiding any deep algebraic result, it applies also to non-rational linear actions.
