For the variety of representations of a tame quiver, we describe a finite stratification into smooth subvarieties that are invariant under the group of base changes and that admit smooth rational geometric quotients. A stratum consists of all representations that differ only in the parameters of the

A conjecture of Kac states that the constant coefficient of the polynomial counting the number of absolutely indecomposable representations of a quiver over a finite field is equal to the multiplicity of the corresponding root in the associated Kac᎐Moody Lie algebra. In this paper we give a combinat
