## Luca Motto Ros: Ultrametric spaces, isometry, and isometry groups

KGRC Research Seminar – 2017-03-30 at 4pm Speaker: Luca Motto Ros (University of Turin, Italy) Abstract: Gao and Kechris proposed in 2003 two somewhat related problems concerning ultrametric spaces, namely: 1) Determine the complexity of the isometry relation on locally compact Polish ultrametric spaces. continue reading…

## Luca Motto Ros: Uniformly continuous and Lipschitz reducibilities on ultrametric Polish spaces

Monday, November 25, 2013, 16.30 Seminar room 0.011, Mathematical Institute, University of Bonn Speaker: Luca Motto Ros (Universität Freiburg) Title: Uniformly continuous and Lipschitz reducibilities on ultrametric Polish spaces Abstract: We analyze the reducibilities induced by, respectively, uniformly continuous, Lipschitz, and nonexpansive functions on arbitrary ultrametric Polish spaces, and give sufficient and necessary (topological) conditions on such spaces for the corresponding degree-structures being well-behaved. continue reading…
