Sequences of nonlinear quasi contractions and fixed points


Kieu Phuong Chi, Erdal Karapinar, Tran Duc Thanh




In this paper, we state some results on the relationship between the convergence of the nonlinear quasi-contractions and the convergence of their fixed point. The observed results certainly extend some existing results on the topic in the literature, including the results of Nadler and Park. We also furnish an illustrative example to demonstrate the validity of the results expressed.
