Abstract
Abstract We present fixed point theorems for nonlinear cyclic mappings under a generalized weakly contractive condition in G-metric spaces. We furnish examples to demonstrate the usage of the results and produce an application to second-order periodic boundary value problems for ODEs. MSC:47H10, 34B15.
Highlights
1 Introduction Nonlinear analysis is a remarkable confluence of topology, analysis and applied mathematics
The fixed point theory is one of the most rapidly growing topics of nonlinear functional analysis. It is a vast and inter-disciplinary subject whose study belongs to several mathematical domains such as classical analysis, differential and integral equations, functional analysis, operator theory, topology and algebraic topology etc
Most important nonlinear problems of applied mathematics reduce to finding solutions of nonlinear functional equations
Summary
Nonlinear analysis is a remarkable confluence of topology, analysis and applied mathematics. Most important nonlinear problems of applied mathematics reduce to finding solutions of nonlinear functional equations (e.g., nonlinear integral equations, boundary value problems for nonlinear ordinary or partial differential equations, the existence of periodic solutions of nonlinear partial differential equations). They can be formulated in terms of finding the fixed points of a given nonlinear mapping on an infinite dimensional function space into itself. Of a fixed point in a complete metric space but will not imply continuity.
