Title On cluster varieties associated with trees
Abstract We will first recall the general framework of cluster algebras and cluster varieties attached to arbitrary quivers. We will then explain what can be said about interesting differential forms on these varieties when the quiver is a tree, and how counting points over finite fields gives a first idea about their cohomology. This will be illustrated with examples, and involve an amusing set of Feynman rules with 3 colors.
