Title: On a generalization of orbit equivalence relations
Abstract
We will introduce the notion of orbit pseudometric, a continuous version of orbit equivalence relation. Then we will generalize the theorem of Kechris and Louveau stating that the relation E_1 is not reducible to any orbit equivalence. As a consequence, we will obtain that the relation E_1 is not reducible to the relation of zero Gromov-Hausdorff distance. The talk will be based on a joint paper with Marek Cúth and Michal Doucha.
