Existence and uniqueness of fixed points are established for a mapping satisfying a new type of contractive condition involving a rational expression on a generalized metric space. Some main results by Ahmad et al. [J. Ahmad, M. Arshad, C. Vetro, Int. J. Anal., 2013 (2013), 6 pages] are extended and generalized, also several particular cases and an illustrative example are given. c 2016 All rights reserved.
