On the embedding rigidity problem for uniformly locally finite coarse spaces

Teng Zhang

In this paper, we construct countable uniformly locally finite metric spaces $X$ and $Y$ such that $C_{u}^{*} (X)$ is isomorphic to a hereditary $C^{*}$ -subalgebra of $C_{u}^{*} (Y)$ , while $X…

Isomorphism rigidity of uniform Roe algebras over arbitrary uniformly locally finite coarse spaces

Teng Zhang

The paper proves that any C*-algebra isomorphism between uniform Roe algebras forces the underlying uniformly locally finite coarse spaces to be bijectively coarsely equivalent, th…
