On the fundamental group of a spherical variety

Friedrich Knop

Published 2024-04-01, updated 2024-09-11Version 2

Let $X=G/H$ be a spherical variety over an algebraically closed field of characteristic $p\ge0$. We compute the $p'$-parts of $\pi_0(H)$ and $\pi_1(X)$ from the spherical system of $X$.
