Finite-time blow-up for Euler and Navier–Stokes equations
Determine whether smooth solutions to the incompressible Euler equations and to the incompressible Navier–Stokes equations admit finite-time singularities (blow-up) on a Riemannian manifold.

One of the most important open problems in dynamical systems and partial differential equations is determining whether the Euler equations (and their viscous version, the Navier-Stokes equations) admit solutions that blow-up in finite time.
