Localization of spherical varieties
Published 11 Mar 2013 in math.RT and math.AG | (1303.2561v3)
Abstract: We prove some fundamental structural results for spherical varieties in arbitrary characteristic. In particular, we study Luna's two types of localization and use it to analyze spherical roots, colors and their interrelation. At the end, we propose a preliminary definition of a p-spherical system.
