- We prove a generating function formula for the Betti numbers of Nakajima quiver
varieties. We prove that it is a q-deformation of the Weyl-Kac character formula.
In particular this implies that the constant term of the polynomial counting the
number of absolutely indecomposable representations of a quiver equals the multiplicity
of a certain weight in the corresponding Kac-Moody algebra, which was conjectured
by Kac in 1982.@eng
