摘要

摘要本文在度量空间的框架下，结合Caristi压缩、Ćirić-拟压缩和弱压缩，引入了一些新的压缩映射类型。利用φ-递减性质证明了完备度量空间上这类映射的一些不动点定理。给出了一些例子来加强我们已建立定理的假设。

Some Fixed Point Theorems Via Combination of Weak Contraction and Caristi Contractive Mapping

Abstract In this paper we introduce some new types of contractive mappings by combining Caristi contraction, Ćirić-quasi contraction and weak contraction in the framework of a metric space. We prove some fixed point theorems for such type of mappings over complete metric spaces with the help of φ-diminishing property. Some examples are given in strengthening the hypothesis of our established theorems.
