Comparison Theorems of Spectral Radius for Splittings of Matrices
Journal of Applied Mathematics, 2014 A class of the iteration method from the double splitting of coefficient matrix for solving the linear system is further investigated. By structuring a new matrix, the iteration matrix of the corresponding double splitting iteration method is presented ...

Stable splitting of bivariate spline spaces by Bernstein-Bézier methods [PDF]
, 2012 We develop stable splitting of the minimal determining sets for the spaces of bivariate C1 splines on triangulations, including a modified Argyris space, Clough-Tocher, Powell-Sabin and quadrilateral macro-element spaces.

A relaxed block splitting preconditioner for complex symmetric indefinite linear systems
Open Mathematics, 2018 In this paper, we propose a relaxed block splitting preconditioner for a class of complex symmetric indefinite linear systems to accelerate the convergence rate of the Krylov subspace iteration method and the relaxed preconditioner is much closer to the ...

On the convergence of two-step modulus-based matrix splitting iteration method
Open Mathematics, 2021 In this paper, based on the relationship between the linear complementarity problem and its reformulated fixed-point equation, we discuss the conditions of the modulus-based type iteration methods. Moreover, we present some convergence results on the two-

Electron tunneling in the germanium/silicon heterostructure with germanium quantum dots: theory
Хімія, фізика та технологія поверхні, 2021 It is shown that electron tunneling through a potential barrier that separates two quantum dots of germanium leads to the splitting of electron states localized over spherical interfaces (a quantum dot – a silicon matrix).
