Abstract
In this paper we study structural and uniqueness questions for Cartan subalgebras of uniform Roe algebras. We characterise when an inclusion B⊆A of C∗-algebras is isomorphic to the canonical inclusion of ℓ∞(X) inside a uniform Roe algebra C∗u(X) associated to a metric space of bounded geometry. We obtain uniqueness results for `Roe Cartans' inside uniform Roe algebras up to automorphism for non-amenable spaces X with property A, and up to inner automorphism when X has finite decomposition complexity.
