On Arnold's formula for the second variation of energy on orbits of 2d vorticities
2:00pm|Simonyi Hall 101 and Remote Access

We consider variational principles related to V. I. Arnold's stability criteria for steady-state solutions of the two-dimensional incompressible Euler equation. Our goal is to investigate under which conditions the quadratic forms defined by the...

3D Navier-Stokes equations: the dynamics of a blow-up
2:00pm|Simonyi Hall 101 and Remote Access

I will present an elementary introduction to the regularity/uniqueness issues for the Navier-Stokes equations. Thanks to the convex integration technique, the h-principle is starting to take shape for the uniqueness problem. It might be possible...
