Non-uniqueness in law for two-dimensional Navier-Stokes equations with diffusion weaker than a full Laplacian
arXiv:2008.04760
Abstract
We study the two-dimensional Navier-Stokes equations forced by random noise with a diffusive term generalized via a fractional Laplacian that has a positive exponent strictly less than one. Because intermittent jets are inherently three-dimensional, we instead adapt the theory of intermittent form of the two-dimensional stationary flows to the stochastic approach presented by Hofmanov, Zhu Zhu (2019, arXiv:1912.11841 [math.PR]) and prove its non-uniqueness in law.
