    Fixed point theorems for (α, ψ)-Meir-Keeler-Khan mappings
    (International Scientific Research Publications, 2015) Redjel,N.; Dehici,A.; Karapınar,E.; Erhan,İ.M.; Mathematics
    In this paper, we establish fixed point theorems for a (α, ψ)-Meir-Keeler-Khan self mappings. The main result of our work is an extension of the theorem of Khan [M. S. Khan, Rend. Inst. Math. Univ. Trieste. Vol VIII, Fase., 10 (1976), 1-4]. We also give some consequences. © 2015 All rights reserved.

    A note on 'Coupled fixed point theorems for α-ψ-contractive-type mappings in partially ordered metric spaces'
    (Springer international Publishing Ag, 2013) Karapinar, Erdal; Agarwal, Ravi P.; Mathematics
    In this paper, we show that some examples in (Mursaleen et al. in Fixed Point Theory Appl. 2012:124, 2012) are not correct. Then, we extend, improve and generalize their results. Finally, we state some examples to illustrate our obtained results.
