Fixed point results for cyclic α–ψϕ-contractions with application to integral equations

摘要

In this paper, we introduce the notions of α–ψϕ-contractive and cyclic α–ψϕ-contractive mappings and establish the existence and uniqueness of fixed points for such mappings in complete metric-like spaces. The results presented here substantially generalize and extend several comparable results in the existing literature, in particular those of Karapinar and Salimi (2013). As an application, we prove new fixed point results for ψϕ-graphic and cyclic ψϕ-graphic contractive mappings. Moreover, some examples and an application to integral equations are given here to illustrate the usability of the obtained results.
