摘要

本文研究集值分析中的不动点理论。本文将几个概念结合在一起,定义了集值收缩,并证明了这种收缩在完备度量空间中有不动点。我们有两个主要定理,其中一个定理用\(\alpha \) -空间的正则性条件代替了多值收缩的连续性要求。这里有一些说明性的例子和推论。并对不动点集进行了稳定性分析。我们证明了与定理中所考虑的映射相关的不动点集是稳定的。在最后一节中,我们讨论了本文主要结果的一些后果。

Fixed point sets of multivalued rational contractions with stability analysis

The present paper is on fixed point theory in set valued analysis. Here putting several concepts together, we define a set valued contraction and establish that such contractions have fixed points in a complete metric space. We have two main theorems in one of which we use \(\alpha \)-regularity condition of the space as a substitute of the continuity requirement on the multivalued contraction. There are some illustrative examples and corollaries. We also perform stability analysis of fixed point sets. We establish that the fixed point sets associated with the mappings we consider in our theorems are stable. In the last section we discuss some consequences of the main results of this paper.
