摘要
In this paper we develop a new technique to prove existence of solutions of Fokker–Planck equations on Hilbert spaces for Kolmogorov operators with nontrace-class second order coefficients or equivalently with an associated stochastic partial differential equation(SPDE)with non-trace-class noise.Applications include stochastic 2D and 3D-Navier–Stokes equations with non-trace-class additive noise.
