Fixed point theory for the cyclic weaker Meir-Keeler function in complete metric spaces Chi-Ming Chen Department of Applied Mathematics National Hsinchu University of Education No. 521 Nanda Rd. Hsinchu City 300 Taiwan Email address ming@ Abstract In this article we introduce the notions of cyclic weaker o -contractions and cyclic weaker -contractions in complete metric spaces and prove two theorems which assure the existence and uniqueness of a 1 fixed point for these two types of contractions. Our results generalize or improve many recent fixed point theorems in the literature. MSC 47H10 54C60 54H25 55M20. Keywords fixed point theory weaker .
