摘要

The long-time behavior in the sense of distributions forstochastic Klein–Gordon–Schrodinger equations in the whole space R~n,1 ≤ n ≤ 3, is studied. First the existence of one stationary measure fromany moment-finite initial data in the space H~1(R~n) x H~1(R~n) x L~2 (R~n ) isproved and then a global measure attractor is constructed in the spaceconsisting of probability measures supported on H~2 (R~2) x H~2(R~n) xBecause of the lack of compact embedding, some a prioriestimates and a split of solutions play important roles in the approach.
