摘要:

考虑一类偏微分包含问题: -Δu∈G(x,u). 当集值函数G(x,u)取有界紧凸值的、 关于变量x是可测的、 关于变量u是闭图像时, 运用Kakutani-Fan不动点定理, 证明了边值解的存在性, 且解集是弱紧的.

关键词: 偏微分包含, 边值解, 不动点

Abstract:

This paper deals with the boundary value problems for a class of partial differential inclusions -Δu∈G(x,u). When G(x,u) takes bounded weakly compact convex values,  is measurable about variable x, and is a closed graph about variable u, using the techniques from the KakutaniFan fixed point theory, we have proved the existence theorems of boundary value solutions of the system and the solution sets are weakly compact.

Key words: partial differential inclusion, boundary value solution, fixed point
