摘要
本文引入一类较广的混合单调集值映射,并讨论它们的耦合拟不动点的存在性,推广并统一了〔1~4〕中的某些概念和结果,得出一些新结论。
This paper introduces a class of wider mixed monotone multifunction, anddiscusses some existence theorems of the coupled quasifixed points for these mappings.Extending and unifying some concepts and results of [1~4],in the meantime, it give somenew results.
