摘要
把自治系统解满足的半群性质推广到非自治系统解满足的共圈性质,给出了非自治动力系统拉回吸引子的存在性,并给出了一类含时滞的非自治系统拉回吸引子存在的充分条件.
In this paper, the author generalized the semigroup property of autonomous systems to the cocycle property, and established the existence theorem of the pullback attractor of the non-autonamous systems. At last, the sufficient condition of the existence of the pullback attractor for a non-autonomous system with delays was proved.
