Coupled Best Proximity Points for Cyclic Kannan and Chatterjea Contractions in CATp(0) Spaces

This paper considers the framework of CATp(0) spaces and analyzes coupled best proximity points for cyclic Kannan and cyclic Chatterjea contractions. The framework is substantial and versatile for em- ploying metric notions and contractive conditions. For each mapping, we establish the existence and uniqueness of the coupled best proximity point. The work gives a step toward investigating the best proximity points in CATp(0) spaces.
