摘要
本文引入了广义凝聚映象的概念.并研究了该类映象不动点的存在性问题,给出其对最近点问题的应用.本文结果改进和推广了引文[1,3,4]中的相应结果.
The purpose of this paper is to introduce the concept of generalized condensingmapping and to study existence problem of fixed point for this kind of mappings.As application,we study the existence problem of nearest point for this kind of mappings.Theresults presented in this paper extend and improve the corresponding results of[1,3,4].
