Nonuniqueness in law for stochastic hypodissipative Navier-Stokes equations
A talk in the Bielefeld Stochastic Afternoon series by
Marco Rehmeier from Bielefeld
| Abstract: |
We study the incompressible hypodissipative Navier--Stokes equations with dissipation exponent $0<\alpha<1/2$ on the three-dimensional torus perturbed by an additive Wiener noise term and prove the existence of an initial condition for which distinct probabilistic weak solutions exist. To this end, we employ convex integration methods to construct a pathwise probabilistically strong solution, which violates a pathwise energy inequality up to a suitable stopping time. This paper seems to be the first in which such solutions are constructed via Beltrami waves instead of intermittent jets or flows in a stochastic setting.
This is joint work with Andre Schenke.
