Abstract :
In this paper, we present some fixed-point theorems for families of weakly non-expansive maps under
some relatively weaker and more general conditions. Our results generalize and improve several results due
to Jungck [G. Jungck, Fixed points via a generalized local commutativity, Int. J. Math. Math. Sci. 25 (8)
(2001) 497–507], Jachymski [J. Jachymski, A generalization of the theorem by Rhoades and Watson for
contractive type mappings, Math. Japon. 38 (6) (1993) 1095–1102], Guo [C. Guo, An extension of fixed
point theorem of Krasnoselski, Chinese J. Math. (P.O.C.) 21 (1) (1993) 13–20], Rhoades [B.E. Rhoades,
A comparison of various definitions of contractive mappings, Trans. Amer. Math. Soc. 226 (1977) 257–
290], and others.
