Embeddings of Homogeneous Spaces in Prime Characteristics

Abstract

Let X be a projective algebraic variety over an algebraically closed field k admitting a homogeneous action of a semisimple linear algebraic group G. Then X can be canonically identified with the homogeneous space G/Gx, where x is a closed point in X and Gx the stabilizer group scheme of x. A group scheme over a field of characteristic 0 is reduced so in… (More)
