Fixed point problems for α-ψ-weakly contractive operators on KST spaces

2017

Using the concept of w-distance we will investigate some existence, uniqueness and Ulam-Hyers stability results for fixed point problems concerning ?-?-weakly contractive operators. Starting at the results of P. Amiri, S. Rezapour, N. Shahzad [1] the presented theorems extend and generalize several results concerning a w-distance.
