In this paper we consider a cyclic $\varphi_A $-contraction mapping defined on a partially ordered orbitally complete metric space and prove some fixed point and best proximity point …
We provide a positive answer to a question raised by Al-Thagafi and Shahzad [Nonlinear Anal. 70 (2009), 3665–3671] about the existence of a best proximity point for a cyclic …
