On the fundamental group of a spherical variety

Friedrich Knop

Let $X = G / H$ be a spherical variety over an algebraically closed field of characteristic $p \geq 0$ . We compute the $p^{'}$ -parts of $π_{0} (H)$ and $π_{1} (X)$ from the spherical system of $X$ …

Classification of reductive real spherical pairs II. The semisimple case

Friedrich Knop, Bernhard Krötz, Tobias Pecher +1

If $g$ is a real reductive Lie algebra and $h < g$ is a subalgebra, then $(g, h)$ is called real spherical provided that…
