Projective normality of complete symmetric varieties
Rocco Chirivi', Andrea Maffei
We prove that in characteristic zero the multiplication of sections of dominant line bundles on a complete symmetric variety is a surjective map. As a consequence the…

The ring of sections of a complete symmetric variety
Rocco Chirivi', Andrea Maffei
We study the ring of sections A(X) of a complete symmetric variety X, that is of the wonderful completion of G/H where G is an adjoint semi-simple group and H is the fixed subgroup…

A remark on quiver varieties andweyl groups
Andrea Maffei
In this paper we define an action of the Weyl group on the quiver varieties $M_{m,\grl}(d,v)$ with generic $(m,\grl)$. To do it we describe a set of generators of the projective ri…
