  This paper presents analogous results of Hua [7][8] on numbers of
representations of quivers over finite fields which respect nilpotent relations
under certain assumptions. A closed formula which counts isomorphism classes of
absolutely indecomposable representations with given dimension vectors is given
and a $q$-deformation of Weyl-Kac denominator identity is established. In
principle, if the numbers of representations are known, then the numbers of
isomorphism classes of absolutely indecomposable representations are known.
