Descripción
Coble defined in his 1929 treatise invariants for cubic surfaces and
quartic curves. We reinterpret these in terms of the root systems of
type E_6 and E_7 that are naturally associated to these varieties,
thereby giving some of his results a more intrinsic treatment. Our
discussion is uniform for all Del Pezzo surfaces of degree 2,3,4 and 5.
