LetGbe a reductive group over an algebraically closed field of characteristic. We study properties of embeddings of spherical homogeneousG-spaces. We look at Frobenius splittings, canonical or by a-th power, compatible with certain subvarieties. We show the existence of rationalG-equivariant resolutions by toroidal embeddings, and give results about cohomology vanishing and surjectivity of restriction maps of global sections of line bundles. We show that the class of homogeneous spaces for which our results hold contains the symmetric homogeneous spaces in characteristicand is closed under parabolic induction.
