Common fixed point theorems for generalized JH-operator classes and invariant approximations

* Correspondence: poom. [email protected] Department of Mathematics, Faculty of Science, King Mongkut’s University of Technology Thonburi (Kmutt), Bangkok 10140, Thailand Abstract In this article, we introduce two new different classes of noncommuting selfmaps. The first class is more general than JH-operator class of Hussain et al. (Common fixed points for JH-operators and occasionally weakly bi...

Some Fixed Point Theorems

Introduction. We wish to summarize here some new asymptotic fixed point theorems. By an asymptotic fixed point theorem we mean roughly a theorem in functional analysis in which the existence of fixed points of a map ƒ is proved with the aid of assumptions on the iterates f of ƒ. Such theorems have proved of use in the theory of ordinary and functional differential equations (see [7], [8], [9] a...
