  • The talk will be devoted to understanding solvable subgroups of arithmetic groups. We will try to classify them up to commensurability by using the ambient algebraic group. We will be able to describe algebraically the maximal ones and we will try to understand their action on the boundary. If time permits we will mention an application to the theory of von Neumann algebras.
