Remarks on b-enriched nonexpansive mappings

In this note, we analyzed the concept of enriched nonexpansive which was proposed in "Approximating fixed points of enriched nonexpansive mappings by Krasnoselskij iteration in Hilbert spaces" (Carpathian J. Math., 35(2019), No. 3, 293-304.) Through our analysis, we conclude that the idea of enriched nonexpansive needs reconsideration, as it coincides with well known concept of nonexpansive. Our findings provide an insights into the existing literature and highlight the need for further investigations and clarifications in the existing literature on a metric-fixed point theory.

Fixed point results of enriched interpolative Kannan type operators with applications

The purpose of this paper is to introduce the class of enriched interpolative Kannan type operators on Banach space that contains the classes of enriched Kannan operators, interpolative Kannan type contraction operators and some other classes of nonlinear operators. Some examples are presented to support the concepts introduced herein. A convergence theorem for the Krasnoselskii iteration method to approximate fixed point of the enriched interpolative Kannan type operators is proved. We study well-posedness, Ulam-Hyers stability and periodic point property of operators introduced herein. As an application of the main result, variational inequality problem is solved.

Fixed point results in R-enriched interpolative Kannan pair in R-Convex metric spaces

The purpose of this paper is to introduce the class of R-enriched interpolative Kannan pair and proved a common fixed point result in the context of R-complete convex metric spaces. Some examples are presented to support the concepts introduced herein. Moreover, we study the well-posedness, limit shadowing property and Ulam-Hyers stability of the mappings introduced herein. Our result extend and generalize several comparable results in the existing literature.

Fixed points of enriched contraction mappings in 2-normed spaces

Very recently, Berinde and Păcurar obtained in [V. Berinde and M. Păcurar, Approximating fixed points of enriched contractions in Banach spaces. Journal of Fixed Point Theory and Applications. \textbf{22}(2) (2020), 1--10.] an interesting generalization of the Banach contractive mapping principle in the framework of Banach spaces. The aim of this paper is to prove some fixed point theorems which extend the results of Berinde and Păcurar to the case of 2-normed spaces.

A generalized Suzuki Berinde contraction that characterizes Banach spaces

We introduce a large class of contractive mappings, called Suzuki Berinde type contraction. We show that any Suzuki Berinde type contraction has a fixed point and characterizes the completeness of the underlying normed space. A fixed point theorem for multivalued mapping is also obtained. These results unify, generalize and complement various known comparable results in the literature.
