Kashaev and Reshetikhin previously described a way to define holonomy invariants of knots using quantum sl 2 at a root of unity. These are generalized quantum invariants depend both on a knot K and a representation of the fundamental group of its complement into SL 2 (C); equivalently, we can think of KR(K) as associating to each knot a function on (a slight generalization of) its character variety. In this paper we clarify some details of their construction. In particular, we show that for K a hyperbolic knot KaRe(K) can be viewed as a function on the geometric component of the A-polynomial curve of K. We compute some examples at a third root of unity.
