E-series of character varieties of non-orientable surfaces

Abstract: In this paper we are interested in two kinds of stacks associated to a compact non-orientable surface Σ. (A) We consider simply the quotient stack of the space of representations of the fundamental group of Σ to GLn. (B) We choose a set S of k-punctures of Σ and a generic k-tuple of semisimple conjugacy classes of GLn, and we consider the stack of anti-invariant local systems on the orientation cover of Σ with local monodromies around the punctures given by the prescribed conjugacy classes. We compute the numb… Show more

“…For a quotient stack X = [X/G] where G is a connected linear algebraic group and X an affine variety, the E-series E(X , q) is well defined and E(X , q) = E(X, q)E(BG, q) where BG is the classifying stack of G, for a proof see [34,Theorem 2.5].…”
