Abstract

In a preprint released in 2016, Daniel Grayson introduces a conjectural presentation of the (higher) relative algebraic KK-groups using purely combinatorial means. In this paper, we will show that this presentation is isomorphic to the classically defined higher relative algebraic KK-groups, and provide some reasons to believe the conjecture posed in this 2016 preprint to be true.
