Abstract:
It is shown that a metric on the union of the sets $X$ and $Y$ determines a Hilbert $C^*$-module over the uniform Roe algebra of the space $X$. Several examples of such Hilbert $C^*$-modules are described in detail.
Keywords:
metric space, Roe algebra, $C^*$-algebra, Hilbert $C^*$-module.
