Common fixed points of noncommuting almost contractions in cone metric spaces. (English) Zbl 1195.54070

Summary: We prove the existence of coincidence points and common fixed points for a large class of almost contractions in cone metric spaces. These results generalize, extend and unify several well-known recent related results in literature.
