Abstract

Given a simple, acyclic dimension group G0G_{0} and countable, torsion-free, abelian group G1G_{1}, we construct a minimal, amenable, \'{e}tale equivalence relation RR on a Cantor set whose associated groupoid CC^{*}-algebra, C(R)C^{*}(R), is tracially AF, and hence classifiable in the Elliott classification scheme for simple, amenable, separable CC^{*}-algebras, and with K(C(R))(G0,G1)K_{*}(C^{*}(R)) \cong(G_{0}, G_{1}).
