Let $X$ be a proper metric space, and let $\{C_k\}_{k=0}^\infty$ be an anti-Cech system of $X$. For each $k$, let $N_{C_k}$ be the nerve space of $C_k$, and let $B_L^p(N_{C_k})$ an…

Let a metric space and its Roe algebra be given, with the Roe algebra encoding coarse geometric information through finite-propagation locally compact operators. The associated K-t…

For a metric space and an operator algebra containing the relevant operators, an operator is quasi-local if it can be approximated in the sense defined in the paper by operators wh…
