SUMMARY:Analysis Seminar
CLASS:PUBLIC
DESCRIPTION:SOHAM CHAKRABORTY\, ÉCOLE NORMALE SUPÉRIEURE \n\nMeasured gro
 upoids and the Choquet-Deny property\n\nA countable discrete group is call
 ed Choquet-Deny if for every\nnon-degenerate probability measure on the gr
 oup\, the corresponding\nspace of bounded harmonic functions is trivial. R
 ecently a complete\ncharacterization of Choquet-Deny groups was obtained b
 y Frisch\,\nHartman\, Tamuz and Ferdowsi. In this talk\, we will look at t
 he\nextension of the Choquet-Deny property to the framework of discrete\nm
 easured groupoids. Our main result gives a complete characterisation\nof t
 his property in terms of the associated measured equivalence\nrelation and
  the isotropy groups of the groupoid. This talk is based\non a joint work 
 with Tey Berendschot\, Milan Donvil\, Mario Klisse and\nSe-Jin Kim.\n\nMC
