New uni-parametric family of multipoint methods with memory for systems of nonlinear equations
Springer Science and Business Media LLC - Tập 74 - Trang 91-113 - 2016
Based on McDougall and Wotherspoon method (Appl Math Lett 29:20–25, 2014) for solving a scalar nonlinear equation, we present a new uni-parametric family of multipoint methods with memory for solving systems of nonlinear equations numerically. The proposed family requires only one Jacobian inversion per iterate and is obtained by using the weight function approach. It is proved that the proposed m...... hiện toàn bộ
Sequential optimality conditions of approximate proper efficiency for a multiobjective fractional programming problem
Springer Science and Business Media LLC - Tập 80 - Trang 611-627 - 2022
In this paper, in the absence of any constraint qualifications, we develop sequential optimality conditions for a constrained multiobjective fractional programming problem characterizing an approximate properly efficient solution. This is achieved by employing a powerful combination of conjugate analysis and the concept of approximate subdifferential. We give an example to present significance of ...... hiện toàn bộ

The many facets of the Estrada indices of graphs and networksAbstract The Estrada index of a graph/network is defined as the trace of the adjacency matrix exponential. It has been extended to other graph-theoretic matrices, such as the Laplacian, distance, Seidel adjacency, Harary, etc. Here, we describe many of these extensions, including new ones, such as Gaussian, Mittag–Leffler and Onsager ones. More importantly, we conte... ... hiện toàn bộ

A multidimensional generalization of some classes of free-derivative iterative methods to solve nonlinear equations
Springer Science and Business Media LLC - Tập 74 - Trang 543-557 - 2016
In this paper we extend to the multidimensional case six free-derivative iterative methods that are known in their scalar version. In order to construct new multidimensional iterative algorithms we develop a new idea based on two operators. All the schemes considered here are two-step methods in which the first step is Steffensen’s method and they have fourth-order local convergence, depending on ...... hiện toàn bộ
A comparison between two-scale asymptotic expansions and Bloch wave expansions for the homogenization of periodic structures
Springer Science and Business Media LLC - Tập 73 - Trang 237-259 - 2016
In this paper we make a comparison between the two-scale asymptotic expansion method for periodic homogenization and the so-called Bloch wave method. It is well-known that the homogenized tensor coincides with the Hessian matrix of the first Bloch eigenvalue when the Bloch parameter vanishes. In the context of the two-scale asymptotic expansion method, there is the notion of high order homogenized...... hiện toàn bộ

Homogenization of a nonstationary convection-diffusion equation in a thin rod and in a layer
Springer Science and Business Media LLC - Tập 58 - Trang 53-95 - 2013
The paper deals with the homogenization of a non-stationary convection-diffusion equation defined in a thin rod or in a layer with Dirichlet boundary condition. Under the assumption that the convection term is large, we describe the evolution of the solution’s profile and determine the rate of its decay. The main feature of our analysis is that we make no assumption on the support of the initial d...... hiện toàn bộ
