Abstract

Best approximation Common fixed point Locally convex space Nonexpansive map Weakly commuting maps
A common fixed-point generalization of the results of Dotson, Tarafdar, and Taylor is obtained which in turn extends a recent theorem by Jungck and Sessa to locally convex spaces. As applications of our work, we improve and unify well-known results on fixed points and common fixed points of best approximation.
