چکیده
|
In 2012, α-ψ-contractive mappings were introduced by samet, vetro and vetro [nonlinear anal., 75(2012), 2154-2165.]. in fact, their technique generalized some ordered fixed point results. recently, salimi, latif and hussain introduced modified α- ψ-contractive mappings [fixed point theory appl., (2013), 2013:151]. first, we show that this notion is not a real generalization for the notion of α-ψ-contractive mappings. also, we provide a new notion entitled new modified α-φ-contractive mappings and show that this notion is a real generalization for some old results.
