Title: "Big" groups of automorphisms of positive entropy
Abstract: I will explain the construction of groups G of birational maps of the complex projective plane satisfying the four following conditions:
 G is isomorphic to SL (2, Z);
 G preserves an elliptic curve;
 all elements of G of infinite order are hyperbolic;
 G is regularizable: up to birational conjugacy, G is a subgroup of Aut(S) where S denotes a projective rational surface.
