Vladimir L. Popov: Two orbits: When is one in the closure of the other?


Submission: 2008, Sep 10

Let $G$ be a connected linear algebraic group, let $V$ be a finite dimensional algebraic $G$-module, and let $\mathcal O_1$, $\mathcal O_2$ be two $G$-orbits in $V$. We describe a constructive way to find out whether or not $\mathcal O_1$ lies in the closure of~$\mathcal O_2$.
