Addendum to "Quivers with loops and perverse sheaves"
arXiv:1509.09302
Abstract
We prove a character formula for the Hopf algebra defined in arXiv:1401.5302 that generalizes quantum groups, as well as for the simple modules associated to dominant integral weights defined in arXiv:1403.0846.
Now part of `On the number of points of nilpotent quiver varieties over finite fields', arXiv:1701.01797
