Representation varieties of twisted Hopf links
Abstract
We study the representation theory of the fundamental group of the complement of a Hopf link with n twists. A general framework is described to analyze the SLr(C)-representation varieties of these twisted Hopf links as byproduct of a combinatorial problem and equivariant Hodge theory. As application, close formulas of their E-polynomials are provided for ranks 2 and 3, both for the representation and character varieties.
