Abstract

In this paper, we study multiplication formula of FF-polynomial of representations of Hernandez and Leclerc's quivers with potentials. Since the truncated qq-characters of some real simple modules over a quantum affine group Uq(g^)U_q(\widehat{\mathfrak{g}}) can be expressed in terms of such FF-polynomials, one can describe the product of two simple modules over Uq(g^)U_q(\widehat{\mathfrak{g}}) using this multiplication formula.

Comments

There is an error: In section 2. Jacobian algebras do in general NOT enjoy the Ext-symmetry which was crucial for the GLS multiplication formula. Morevor, the generalized preprojective are in general NOT Jacobian algebras because the nilpotency relations of the loops don't come from the potential
