## Stochastic weak attractor for a dissipative Euler equation.(English)Zbl 0941.35073

Summary: A nonautonomous dynamical system is considered, a stochastic one that is obtained from the dissipative Euler equation subject to a stochastic perturbation an additive noise. Absorbing sets are defined as sets that depend on time and attract from $$-\infty$$. A stochastic weak attractor is constructed in phase space with respect to two metrics and is shown to be compact in the lower one.
