• Complete symmetric variety
• Projective normality

Let G be a semisimple and simply connected algebraic group, and let H-0 be the subgroup of points fixed by an involution of G. Let V be an irreducible representation of G with a nonzero vector v fixed by H-0. In this article, we prove a property of the normalization of the coordinate ring of the closure of G . [v] in P(V)
