Markov solutions for the 3D stochastic Navier–Stokes equations with state dependent noise

We construct a Markov family of solutions for the 3D Navier-Stokes equations perturbed by a non degenerate noise. We improve the result of 3] in two directions. We see that in fact not only a transition semigroup but a Markov family of solutions can be constructed. Moreover, we consider a state dependant noise. Another feature of this work is that we greatly simplify the proofs of 3]. Dedicated to Giuseppe Da Prato on the occasion of his 70th birthday
