EPPA for two-graphs and antipodal metric spaces
David Evans, Jan Hubička, Matěj Konečný +1
We prove that the class of finite two-graphs has the extension property for partial automorphisms (EPPA, or Hrushovski property), thereby answering a question of Macpherson. In oth…
A combinatorial proof of the extension property for partial isometries
Jan Hubička, Matěj Konečný, Jaroslav Nešetřil
We present a short and self-contained proof of the extension property for partial isometries of the class of all finite metric spaces.
Forbidden cycles in metrically homogeneous graphs
Jan Hubička, Michael Kompatscher, Matěj Konečný
In a recent paper by a superset of the authors it was proved that for every primitive 3-constrained space of finite diameter from Cherlin's catalogue of metrically homogene…
Automorphism groups and Ramsey properties of sparse graphs
David M. Evans, Jan Hubička, Jaroslav Nešetřil
We study automorphism groups of sparse graphs from the viewpoint of topological dynamics and the Kechris, Pestov, Todorčević correspondence. We investigate amenable and extremely a…
