DESCRIPTION:Title: <a href="https://researchseminars.org/talk/RJWAPDE/18/"
 >Recent Advances Concerning the Navier-Stokes and Euler Equations</a>\nby 
 Edriss S. Titi (U. Cambridge\, Texas A&M U. and Weizmann Institute of Scie
 nce) as part of Rio de Janeiro webinar on analysis and partial differentia
 l equations\n\n\nAbstract\nIn this talk I will discuss some recent progres
 s concerning the Navier-Stokes and Euler equations of incompressible fluid
 . In particular\, issues concerning the lack of uniqueness using the conve
 x integration machinery and their physical relevance. Moreover\, I will sh
 ow the universality of the critical $1/3$ H\\"older exponent\, conjectured
  by Onsager for the preservation of energy in Euler equations\, by extendi
 ng the Onsager conjecture for the preservation of generalized entropy in g
 eneral conservation laws.  In addition\, I will present a blow-up criterio
 n for the 3D Euler equations based on a class of inviscid regularization f
 or these equations and the effect of physical boundaries on the potential 
 formation of singularity.\n
