Abstract:
证明了非自治吊桥方程当非线性项 ??g〖JB((〗u,t〖JB))〗?? 和外力项 ??f〖JB((〗x,t〖JB))〗?? 都与时间 ??t?в泄厍? ??g〖JB((〗u,t〖JB))〗?? 平移有界时解的渐近性行为, 并由此获得了方程在 ??H??2〖JB((〗0,L〖JB))〗∩H??1??0〖JB((〗0,L〖JB))〗×L??2〖JB((〗0,L〖JB))〗?? 中的拉回 ?И?D???? 吸引子的存在性.
We prove the asymptotic compactness of process for the non autonomous suspension bridge equations with a nonlinearity ??g〖JB((〗u,t〖JB))〗?? and a forcing term ??f〖JB((〗x,t〖JB))〗??, and ??g〖JB((〗u,t〖JB))〗?? is translation bounded. Furthermore, we obtain the pullback ?И?D???? attractor in ??H??2〖JB((〗0,L〖JB))〗∩H??1??0〖JB((〗0,L〖JB))〗×L??2〖JB((〗0,L〖JB))
