Topics on the Euler and Navier-Stokes equations
Frequency
Only this year
Summary
This topics course focuses on recent and classical fundamental results on the Euler and Navier-Stokes equations, such as global existence of weak solutions, (non)uniqueness results, blow-ups, partial regularity, anomalous dissipation.
Content
The course regards the mathematical theory of the three-dimensional Euler and Navier–Stokes equations. It provides self-contained proofs of some of the most significant results in the area, many of which can only be found in research papers. The first part of the course is dedicated to Elgindi's result on blow-up of solutions of 3D Euler. The second part of the course, include a selection of topics between the following list: the existence of global-in-time Leray–Hopf weak solutions for Navier-Stokes and the local existence of strong solutions; the conditional local regularity results of Prodi-Serrin; the partial regularity results of Caffarelli, Kohn, and Nirenberg; nonuniqueness results obtained via convex integration or instability; anomalous dissipation.
Keywords
