摘要:

考虑一类发展包含在Banach空间中的反周期问题, 集值函数G(t,x)取有界紧凸值的, 关于变量t是可测的, 关于变量x是闭图像, 运用Kakutani-Fan不动点定理, 对方程做了先验估计, 给出了解存在的充分条件, 并证明了解集是弱紧的.

关键词: 发展包含, 反周期, 不动点

Abstract:

The authors discussed the antiperiodic problems for a class of evolution inclusions in Banach space. When the mutilfuction G(t,x)
takes a bounded, weakly compact, convex value, and is measurable about variable t, is a closed graph about variable x, using techniques from the Kakutani-Fan fixed point theory, we have got a priori estimate to this equation and a sufficient condition of the existence of solutions, and proved the solution set is weakly compact.

Key words: evolution inclusion, antiperiodic, fixed point
