Abstract: This paper deals with the asymptotic behavior of solutions of the stochastic $g$-Navier-Stokes equation driven by nonlinear noise. The existence and uniqueness of weak pullback mean random attractors for the equation in Bochner space is proven for when the diffusion terms are Lipschitz nonlinear functions. Furthermore, we also establish the existence of invariant measures for the equation.

Key words: non-Newtonian fluid, weak pullback attractor, mean random dynamical system, nonlinear noise, invariant measure
