The aim of this paper is to establish some fixed point, coincidence point, coupled coincidence point and coupled common fixed point results of an almost generalized \((\phi , \psi , \theta )\)-contractive mappings in ordered b-metric spaces. Our results generalize, extend and unify most of the fundamental metrical fixed point theorems in the existing literature. Few examples are illustrated to justify our results.

$$(\phi , \psi ,\theta )$$ ( ϕ , ψ , θ ) - 有序 b 度量空间中的收缩映射的一些不动点结果

本文的目的是建立一些不动点、重合点、耦合重合点和耦合公共不动点结果的几乎广义的\((\phi , \psi , \theta )\) -有序b度量的收缩映射空间。我们的结果概括、扩展和统一了现有文献中的大多数基本度量不动点定理。很少有例子来证明我们的结果。
