A non-de Finetti theorem for countable Euclidean spaces
Colin Jahel, Pierre Perruchaud
The classical de Finetti Theorem classifies the -invariant probability measures on . More precisely it states that those invariant measu…
Unitary Representations of the Isometry Groups of Urysohn Spaces
Rémi Barritault, Colin Jahel, Matthieu Joseph
We obtain a complete classification of the continuous unitary representations of the isometry group of the rational Urysohn space . As a consequence, we show…
Quasi-invariant measures concentrating on countable structures
Clinton Conley, Colin Jahel, Aristotelis Panagiotopoulos
Countable -structures whose isomorphism class supports a permutation invariant probability measure in the logic action have been characterized by Ackerma…
When invariance implies exchangeability (and applications to invariant Keisler measures)
Samuel Braunfeld, Colin Jahel, Paolo Marimon
We study the problem of when, given a countable homogeneous structure and a space of expansions of , every -invariant probability measure on is exch…
Extension property for partial automorphisms of the -partite and semigeneric tournaments
Jan Hubička, Colin Jahel, Matěj Konečný +1
We present a proof of the extension property for partial automorphisms (EPPA) for classes of finite -partite tournaments for , and for the class of finit…
