DESCRIPTION:Frédéric Chapoton\, CNRS Université de Strasbourg\nCluster 
 algebras were introduced by Fomin and Zelevinsky to study\ntotal positivit
 y and canonical bases. They have since been used in many different subject
 s.\nCluster algebras are commutative algebras\, hence one can look at them
  from a geometric\npoint of view and study the associated cluster varietie
 s. I will describe some results about\nthe class of cluster varieties asso
 ciated with trees\, dealing in particular with numbers\nof points over fin
 ite fields and cohomology rings.
