A proof of the Mazur-Orlicz theorem via the Markov-Kakutani common fixed point theorem, and vice versa

摘要

In this paper, we present a new proof of the Mazur-Orlicz theorem, which uses the Markov-Kakutani common fixed point theorem, and a new proof of the Markov-Kakutani common fixed point theorem, which uses the Mazur-Orlicz theorem.
