Fixed points of Kannan-type mapping to control function

Abstract

The purpose of this paper is to extend the results of R. Kannan [1] and J. Górnicki [2] to the class of strong b-metric spaces. Specifically, we use the control function to establish some sufficient conditions for Kannan-type mapping to have only fixed points and for Picard iterations to converge to fixed points in the strong b-metric space.
