摘要

我们计算了g = 3属的复曲线的基本群到SL(2, C)的表示的模空间的e多项式，以及扭曲表示的模空间的e多项式。g = 1,2的情况已经在[12]中做过了。我们遵循[12]中介绍的几何技术，基于对表示空间的分层，以及对颤振下e多项式行为的分析。

E-polynomials of $\mathrm{SL}(2, \mathbb{C})$-character varieties of complex curves of genus $3$

We compute the E-polynomials of the moduli spaces of representations of the fundamental group of a complex curve of genus g = 3 into SL(2, C), and also of the moduli space of twisted representations. The case of genus g = 1, 2 has already been done in [12]. We follow the geometric technique introduced in [12], based on stratifying the space of representations, and on the analysis of the behaviour of the E-polynomial under fibrations.
