Abstract

Given a self-mapping g : A A and a non-self-mapping T : A B , the aim of this work is to provide sufficient conditions for the existence of a unique point x A , called g-best proximity point, which satisfies d g x , T x = d A , B . In so doing, we provide a useful answer for the resolution of the nonlinear programming problem of globally minimizing the real valued function x d g x , T x , thereby getting an optimal approximate solution to the equation T x = g x . An iterative algorithm is also presented to compute a solution of such problems. Our results generalize a result due to Rhoades (2001) and hence such results provide an extension of Banach's contraction principle to the case of non-self-mappings.
