摘 要: 本文引进了一类新的压缩算子,即二元φ-序压缩算子,并且在完备的半序度量空间(其中的半序由φ所导出)上证明了几个二元φ-序压缩算子的不动点定理.本文所得的部分结论推广了最近一些文献中相应的结论. In this paper,the binary φ-ordered contractive operator as a new type contractive operator is introduced,and some fixed point theorems of binary φ-ordered contractive operators are proved in a complete metric space,in which the partial ordering is induced by the mapping φ.Part of these results generalize the corresponding results in present papers.
