Care tutte, cari tutti, per il prossimo evento del ciclo dei Seminari di Analisi, martedì 10 dicembre alle ore 15, in Aula Magna, avremo il piacere di ascoltare Edriss Titi (Cambridge), che terrà un seminariohttps://www.dm.unipi.it/en/seminar/?id=6745ed3a047fd213275218bc dal titolo "Recent Advances Concerning the Navier-Stokes and Euler Equations". Trovate l'abstract qui sotto.

Approfittiamo per ricordare che il Professor Titi terrà anche i seguenti seminari presso la SNS:

* Lunedì 9, ore 16 in Aula Dini (Palazzo del Castelletto) ci sarà il Colloquio De Giorgi, con una lecture dal titolo "Is dispersion a stabilizing or destabilizing mechanism? Landau-damping induced by fast background flows”. Trovate quihttp://www.crm.sns.it/course/7064/ l’abstract. * Mercoledì 11, ore 15, ci sarà il Seminari della Classe di Scienze, e terrà un talk non tecnico aperto ad un pubblico (anche) non specialistico dal titolo “Mathematics of Turbulent Flows: A Million Dollar Problem!"

A presto, Ilaria Lucardesi e Luigi Forcella

Title: Recent Advances Concerning the Navier-Stokes and Euler Equations

Abstract: In this talk we will discuss some recent progress concerning the Navier-Stokes and Euler equations of incompressible fluid. In particular, issues concerning the lack of uniqueness using the convex integration machinery and their physical relevance. Moreover, we will show the universality of the critical 1/3 H"older exponent, conjectured by Onsager for the preservation of energy in Euler equations, by extending the Onsager conjecture for the preservation of generalized entropy in general conservation laws. In addition, we will present a blow-up criterion for the 3D Euler equations based on a class of inviscid regularization for these equations and the effect of physical boundaries on the potential formation of singularity. ----------- Luigi Forcella, Assistant Professor (RTD-B, tenure-track) University of Pisa Department of Mathematics Largo Bruno Pontecorvo 5 57127 Pisa, Italy
