DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GaTO/45/">Or
 bit equivalence rigidity of irreducible actions of right-angled Artin grou
 ps</a>\nby Camille Horbez (Orsay) as part of Geometry and topology online\
 n\n\nAbstract\n<p>A central goal in measured group theory is to classify f
 ree\, ergodic\, measure-preserving actions of countable groups on probabil
 ity spaces up to orbit equivalence: that is\, up to the existence of a mea
 sure space isomorphism sending orbits to orbits. Rigidity occurs when orbi
 t equivalence of two actions forces them to be conjugate through a group i
 somorphism. In this talk\, I will present orbit equivalence rigidity pheno
 mena for actions of (centerless\, one-ended) right-angled Artin groups\, u
 pon imposing that every standard generator acts ergodically on the space.\
 n\n<p>This is joint work with Jingyin Huang.\n
