  Moduli Space of Marked Cubic Surfaces

ABSTRACT: I will first explain what marked cubic surfaces are and the action of the Weyl group of the root system E6 on their moduli space. Then I will describle an equivariant rational map from this moduli space to the projectivised complexified root lattice.
