Luca Motto Ros: Ultrametric spaces, isometry, and isometry groups
KGRC Research Seminar – 20170330 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 degreestructures being wellbehaved. continue reading…

6th Young Set Theory Workshop, June 1014, 2013
The workshop wil take place in Oropa (PiemonteItaly) in a congress center located in a medieval sanctuary in the midst of the alpine region of north west Piemonte. The aims of the “Young Set Theory Workshops” are to bring together young researchers in the domain of set theory and give them the opportunity to learn from each other and from experts in a friendly environment. continue reading…
