摘要:

考虑一类偏微分包含边值问题: -Δ u∈ext G(x,u). 当集值函数G(x,u)为有界紧凸值的、 关于变量x是可测的、 关于变量u是连续的时, 利用Tolstonogov端点连续选择定理, 证明了其端点解的存在性.

关键词: 偏微分包含, 端点解, 不动点

Abstract:

This paper deals with the boundary value problems for a class of partial differential inclusions -Δ u∈ext G(x,u). When 
G(x,u) takes bounded, weakly compact, convex values, and is measurable about variable x, is continuous about variable u, we proved the existence of extremal solutions on the basis of Tolstonogov extremal continuous selection theorem.

Key words: partial differential inclusion, extremal solution, fixed point
