# Common fixed points and invariant approximation of $R$-subweakly commuting maps in convex metric spaces

Abstract

Sufficient conditions for the existence of a common fixed point of $R$-subweakly commuting mappings are established within the framework of a convex metric space. As applications, we obtain various results on the best approximation for this class of mappings generalizing the results known from the literature.
