Filters, topologies, the Rado graph, and the Urysohn space
Abstract
My work with Anatoly Vershik concerned automorphism groups of the Rado graph and homeomorphism groups of the Urysohn space. This paper contains some further thoughts on these issues, together with connections to topologies and filters on countable sets.
