摘要

我们证明，任何连通的还原代数群 $G$ 的邻接表示的每个轨道都是有理代数品种。对于复杂简单相连的半简单 $G$，这意味着同质仿射哈密顿 $G$ 变体的合理性（我们对其进行了分类）。

Rationality of adjoint orbits

We prove that every orbit of the adjoint representation of any connected reductive algebraic group $G$ is a rational algebraic variety. For complex simply connected semisimple $G$, this implies rationality of homogeneous affine Hamiltonian $G$-varieties (which we classify).
