Common coincidence points for Nadler’s type hybrid fuzzy contractions
Springer Science and Business Media LLC - Tập 2023 - Trang 1-18 - 2023
Shazia Kanwal, Shumaila Maham, Mohammed Shehu Shagari, OM Kalthum S. K. Mohamed, Arafa O. Mustafa, Awad A. Bakery
In the framework of complete metric spaces, the major objective of this paper is to investigate if a common coincidence point exists for more than two fuzzy mappings meeting the criteria of hybrid fuzzy contractions of Nadler’s type in connection with the Hausdorff metric. Fascinating examples are also provided to show how the strategy can be used. For the presence of a common α-fuzzy fixed point ... hiện toàn bộ
An extended data envelopment analysis for the decision-making
Springer Science and Business Media LLC - Tập 2017 - Trang 1-16 - 2017
Xiao-Li Meng, Fu-Gui Shi
Based on the CCR model, we propose an extended data envelopment analysis to evaluate the efficiency of decision making units with historical input and output data. The contributions of the work are threefold. First, the input and output data of the evaluated decision making unit are variable over time, and time series method is used to analyze and predict the data. Second, there are many sample de... hiện toàn bộ
Regional division and reduction algorithm for minimizing the sum of linear fractional functions
Springer Science and Business Media LLC - Tập 2018 - Trang 1-19 - 2018
Pei-Ping Shen, Ting Lu
This paper presents a practicable regional division and cut algorithm for minimizing the sum of linear fractional functions over a polyhedron. In the algorithm, by using an equivalent problem (P) of the original problem, the proposed division operation generalizes the usual standard bisection, and the deleting and reduction operations can cut away a large part of the current investigated region in... hiện toàn bộ

We give a discrete Grüss type inequality on fractional calculus.
A New Projection Algorithm for Generalized Variational Inequality
Springer Science and Business Media LLC - Tập 2010 - Trang 1-8 - 2010
Changjie Fang, Yiran He
We propose a new projection algorithm for generalized variational inequality with multivalued mapping. Our method is proven to be globally convergent to a solution of the variational inequality problem, provided that the multivalued mapping is continuous and pseudomonotone with nonempty compact convex values. Preliminary computational experience is also reported.

On fixed points of rational contractions in generalized parametric metric and fuzzy metric spaces
Springer Science and Business Media LLC - Tập 2021 - Trang 1-15 - 2021
Thounaojam Stephen, Yumnam Rohen, Nabil Mlaiki, Mairembam Bina, Nawab Hussain, Doaa Rizk
We introduce the notion of generalized parametric metric spaces along with the study of its various properties. Further, we prove some new fixed point theorems for $(\alpha ,\psi )$ -rational-type contractive mappings in generalized parametric metric spaces. As a consequence, we deduce fixed point theorems for $(\alpha , \psi )$ -rational-type contractive mappings in partially ordered rectangular ... hiện toàn bộ
Approximate weakly efficient solutions of set-valued vector equilibrium problems
Springer Science and Business Media LLC - Tập 2018 - Trang 1-17 - 2018
Jian Chen, Yihong Xu, Ke Zhang
In this paper, we introduce a new kind of approximate weakly efficient solutions to the set-valued vector equilibrium problems with constraints in locally convex Hausdorff topological vector spaces; then we discuss a relationship between the weakly efficient solutions and approximate weakly efficient solutions. Under the assumption of near cone-subconvexlikeness, by using the separation theorem fo... hiện toàn bộ
Refined converses of Jensen’s inequality for operators
Springer Science and Business Media LLC - Tập 2013 - Trang 1-20 - 2013
Jadranka Mićić, Josip Pečarić, Jurica Perić
In this paper converses of a generalized Jensen’s inequality for a continuous field of self-adjoint operators, a unital field of positive linear mappings and real-valued continuous convex functions are studied. New refined converses are presented by using the Mond-Pečarić method improvement. Obtained results are applied to refine selected inequalities with power functions. MSC:47A63, 47A64.
