DESCRIPTION:It has been well-accepted for a long time that turbulence requ
 ires a probabilistic description. Accordingly\, concepts of statistical so
 lution for the Navier-Stokes equations were introduced by Foias and Vishik
 -Fursikov in the 1970s. In contrast\, similar notions for the Euler equati
 ons have received comparatively little attention. We show how the determin
 istic existence theory for the 2D Euler equations with unbounded vorticity
  (even in the Delort class) can be established in the statistical context\
 , and discuss the relation with the measure-valued solutions of DiPerna-Ma
 jda and the Young measure-based statistical solution concept of Fjordholm-
 Lanthaler-Mishra. This is joint work with Raphael Wagner.&nbsp\;
