【摘要】:本文利用序方法將半序集上一些經(jīng)典的不動(dòng)點(diǎn)定理進(jìn)行了推廣,得到了若干擬序集上非線性算子的廣義不動(dòng)點(diǎn)定理,主要結(jié)果如下:1.在擬序集上提出了A=CB型和∑i=1mCiBi型增算子的概念,用序方法研究了4=CB型和∑i=1m CiBi型增算子的不動(dòng)點(diǎn)的問題,得出了A=CB型和∑i=1m CiBi型增算子在不具備連續(xù)性的情況下存在最小和最大廣義不動(dòng)點(diǎn).2.在擬序Banach空間上提出了正規(guī)楔的概念,用序與拓?fù)湎嘟Y(jié)合的方法研究了擬序Banach空問中全擬序子集列緊性的性質(zhì)及算子的不動(dòng)點(diǎn)的存在性問題,得出了擬序Banach空間中全擬序子集列緊性等價(jià)于弱列緊性及其上增算子的廣義不動(dòng)點(diǎn)的存在性.3.在擬序集上提出了混合單調(diào)算子及其廣義耦合不動(dòng)點(diǎn)的概念,用序方法研究了混合單調(diào)算子的廣義耦合不動(dòng)點(diǎn)的問題,得出了擬序集上混合單調(diào)算子在不具備連續(xù)性的情況下存在最小和最大廣義耦合不動(dòng)點(diǎn).
[Abstract]:In this paper, we generalize some classical fixed point theorems on semi-ordered sets by using the ordering method, and obtain some generalized fixed point theorems for nonlinear operators on quasi-ordered sets. The main results are as follows: 1. In this paper, the concepts of A=CB type and 鈭,
