Abstract

We study the topological dynamics of the action of the diagonal subgroup on quotients Gamma(2,R)*PSL(2,R), where Gamma is an irreducible lattice. Closed orbits are described and a set of points of dense orbit is explicitly given. Such properties are expressed using the Furstenberg boundary of the symmetric space H*H.
