Topology of character varieties and representations of quivers
Abstract In Hausel et al. (2008) [10] we presented a conjecture generalizing the Cauchy formula for Macdonald polynomial. This conjecture encodes the mixed Hodge polynomials of the character varieties of representations of the fundamental group of a punctured Riemann surface of genus g . We proved several results which support this conjecture. Here we announce new results which are consequences of those in Hausel et al. (2008) [10] .
