When does isomorphism of uniform Roe algebras associated imply coarse equivalence of the underlying coarse spaces?
A recent result of Spakula and Willett gives sufficient conditions in the case of coarse metric spaces. These conditions are uniform
discreteness and property A (the `coarse' analogue of amenability). I’ll discuss recent progress on weakening these conditions.
No previous knowledge of coarse spaces, Roe algebras, or logic is required.
