Some new generalizations of F−contraction type mappings that weaken certain conditions on Caputo fractional type differential equations

Abstract

In this paper, firstly, we introduce some new generalizations of F−contraction, F−Suzuki contraction, and F−expanding mappings. Secondly, we prove the existence and uniqueness of the fixed points for these mappings. Finally, as an application of our main result, we investigate the existence of a unique solution of an integral boundary value problem for scalar nonlinear Caputo fractional differential equations with a fractional order (1, 2).
