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

Generalized spaces of double sequences for Orlicz functions and bounded-regular matrices over n-normed spaces
Springer Science and Business Media LLC - Tập 2014 - Trang 1-16 - 2014
Syed Abdul Mohiuddine, Kuldip Raj, Abdullah Alotaibi
The aim of this paper is to introduce some generalized spaces of double sequences with the help of the Musielak-Orlicz function and four-dimensional bounded-regular (shortly, RH-regular) matrices ...... hiện toàn bộ
Bounds for the M-spectral radius of a fourth-order partially symmetric tensor
Springer Science and Business Media LLC - Tập 2018 Số 1 - Trang 1-7 - 2018
Li, Suhua, Li, Yaotang
M-eigenvalues of fourth-order partially symmetric tensors play an important role in many real fields such as quantum entanglement and nonlinear elastic materials analysis. In this paper, we give two bounds for the maximal absolute value of all the M-eigenvalues (called the M-spectral radius) of a fourth-order partially symmetric tensor and discuss the relation of them. A numerical example is given...... hiện toàn bộ
On the unconstrained optimization reformulations for a class of stochastic vector variational inequality problems
Springer Science and Business Media LLC -
Di Dong, Guo-ji Tang, Hang Qiu
AbstractIn this paper, a class of stochastic vector variational inequality (SVVI) problems are considered. By employing the idea of a D-gap function, the SVVI problem is reformulated as a deterministic model, which is an unconstrained expected residual minimization (UERM) problem, while it is reformulated as a constrained expected residual minimization problem in t...... hiện toàn bộ
A method with inertial extrapolation step for convex constrained monotone equations
Springer Science and Business Media LLC - Tập 2021 Số 1 - 2021
Abdulkarim Hassan Ibrahim, Poom Kumam, Auwal Bala Abubakar, Jamilu Abubakar
AbstractIn recent times, various algorithms have been incorporated with the inertial extrapolation step to speed up the convergence of the sequence generated by these algorithms. As far as we know, very few results exist regarding algorithms of the inertial derivative-free projection method for solving convex constrained monotone nonlinear equations. In this articl...... hiện toàn bộ
Some relationships among the constraint qualifications for Lagrangian dualities in DC infinite optimization problems
Springer Science and Business Media LLC - Tập 2015 - Trang 1-14 - 2015
Donghui Fang
In this paper, we establish some relationships among several constraint qualifications, which characterize strong Lagrangian dualities and total Lagrangian dualities for DC infinite optimization problems.
Approximate controllability of second-order impulsive neutral stochastic differential equations with state-dependent delay and Poisson jumps
Springer Science and Business Media LLC - Tập 2023 - Trang 1-26 - 2023
Hao Huang, Zheng Wu, Xiaofeng Su
We consider the approximate controllability for a class of second-order impulsive neutral stochastic differential equations with state-dependent delay and Poisson jumps in a real separable Hilbert space. Under the sufficient conditions, we obtain approximate controllability results by virtue of the theory of a strongly continuous cosine family of bounded linear operators combined with stochastic i...... hiện toàn bộ
