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 KacแMoody Lie algebra. In this paper we give a combinat
In this paper we study a certain involution `: Z S + ร Z S + which we call the multisegment duality. This involution acts on the free abelian semigroup Z S + whose generators are indexed by the set S=S r of pairs of integers (i, j) such that 1 i j r (throughout the paper, r will be a fixed positive
