Virtual Hodge polynomials of the moduli spaces of representations of degree 2 for free monoids
Kazunori Nakamoto, Takeshi Torii
In this paper we study the topology of the moduli spaces of representations of degree for free monoids. We calculate the virtual Hodge polynomials of the character varieties fo…
