Abstract:

We complement the characterization of the graph products of cyclic groups G(\Gamma, {\mathfrak p}) admitting a Polish group topology of [9] with the following result. Let G = G(\Gamma, {\mathfrak p}), then the following are equivalent: [i] there is a metric on \Gamma which induces a separable topology in which E_{\Gamma} is closed; [ii] G(\Gamma, {\mathfrak p}) is embeddable into a Polish group; [iii] G(\Gamma, {\mathfrak p}) is embeddable into a non-Archimedean Polish group. We also construct left-invariant separable group ultrametrics for G = G(\Gamma, {\mathfrak p}) and \Gamma a closed graph on the Baire space, which is of independent interest. - published version (7p)
