PHYSICS ??-?? ??????? ???? (??-?? ????? ????) ... 14:00 - 16:00 Mathematical Logic Weekly Seminar Polish ultrametric spaces, their isometry groups, and generalized wreath products School MATHEMATICS We address Krasner's problem (1956) for Polish ultrametric spaces and provide a (hopefully) satisfactory solution. In particular, we discuss a correspondence between the isometry groups of Polish ultrametric spaces belonging to some natural subclasses and various collections of generalized wreath products proposed in the literature. This is joint work with R. Camerlo and A. Marcone.
