Introduction: Orlicz and Birnbaum considered spaces of functions with growth properties different from the power type growth control, provided by the p L -norm. This generalization found many applications in differential and integral equations with kernels of non-power types. A more abstract approach was given by Nakano in connection with the theory of order spaces. His point of view was genera...

In this paper, we introduce the notion of fuzzy R−ψ−contractive mappings and prove some relevant results on existence uniqueness fixed points for type in setting non-Archimedean metric spaces. Several illustrative examples are also given to support our newly proven results. Furthermore, apply main a solution Caputo fractional differential equations.

We set up two new variants ofψ -contractive mappings designed for two and three maps in metric spaces and originate common fixed point theorems for T -strictly weakly isotone increasing mappings and relatively weakly increasing mappings in complete ordered metric spaces. To demonstrate our results, we give some examples throughout the paper. At the same time, as applications of the presented th...
