Stabilizers for ergodic actions and invariant random expansions of non-archimedean Polish groups
Colin Jahel, Matthieu Joseph
Let be a closed permutation group on a countably infinite set , which acts transitively but not highly transitively. If is oligomorphic, has no algebraicity and weakly e…
Invariant measures on products and on the space of linear orders
Colin Jahel, Todor Tsankov
Let be an -categorical structure and assume that has no algebraicity and has weak elimination of imaginaries. Generalizing classical theorems of de Finetti and Ry…
Minimal model-universal flows for locally compact Polish groups
Colin Jahel, Andy Zucker
Let be a locally compact Polish group. A metrizable -flow is called model-universal if by considering the various invariant probability measures on , we can recover e…
Unique ergodicity of the automorphism group of the semigeneric directed graph
Colin Jahel
We prove that the automorphism group of the semigeneric directed graph (in the sense of Cherlin's classification) is uniquely ergodic.
Topological dynamics of Polish group extensions
Colin Jahel, Andy Zucker
We consider a short exact sequence of Polish groups and consider what can be deduced about the dynamics of given information about the dynamics of a…
