Title: "From invariant theory to meromorphic automorphic forms and vice versa."
A Riemann surface of genus one is given up to isomorphism by a smoothcubic curve up to a projective linear transformation, but also by a point in theupper half plane up to a modular transformation. This fact is at the origin of oneof the highlights of 19th century mathematics, namely the identification of theinvariant theory of cubic forms in three variables with the theory of automorphicforms in one variable.In recent yearssome intrigueing higher dimensional analogues of this identificationhave been found. We shall review some of these.
