Abstract:The main aim of this research endeavor is to introduce a novel type of generalized metric space, termed an extended (ϕ, ψ)‐metric space, to establish new fixed point results and employ them to prove the existence and uniqueness of solutions to first‐order differential equations. To achieve this goal, we introduce the concepts of (α, θ)‐admissible Banach contraction, (α, θ)‐admissible crooked Banach contraction, and (α, θ)‐admissible (φ, β)‐contraction in an extended (ϕ, ψ)‐metric space. We augment our theoreti… Show more
