SUMMARY:The effect of intermittency on regularity properties of the soluti
 ons to the Navier-Stokes equations - Alexey Cheskidov (University of Illin
 ois at Chicago\, Institute for Advanced Study\, Princeton)

DESCRIPTION:In this talk I will discuss the notion of intermittency in flu
 ids. Eddies do not occupy the whole space in intermittent turbulent flows\
 , which leads to a more efficient energy cascade mechanism. Hence\, highly
  intermittent solutions of the Navier-Stokes equations can potentially exh
 ibit pathological behaviors\, such as loss of uniqueness. Convex integrati
 on schemes produce examples of such solutions\, and I will discuss the rol
 e of spacial and temporal intermittency in such constructions.
