| Abstract: | In this paper, we first present an existence theorem of zero points for functionals in convex metric spaces, and then use this theorem to study the extreme value problem for functionals and the existence problems of common fixed points and coincidence points for mappings in convex metric spaces. The results obtained in this paper generalize and improve some results in . |
