A Comparison Study of the Classical and Modern Results of Semi-Local Convergence of Newton-Kantorovich Iterations

open access: yesMathematics, 2022
There are a plethora of semi-local convergence results for Newton’s method (NM). These results rely on the Newton–Kantorovich criterion. However, this condition may not be satisfied even in the case of scalar equations.

Notions of optimal transport theory and how to implement them on a computer [PDF]

open access: yes, 2017
This article gives an introduction to optimal transport, a mathematical theory that makes it possible to measure distances between functions (or distances between more general objects), to interpolate between objects or to enforce mass/volume ...

Numerical treatment of singularly perturbed unsteady Burger-Huxley equation

open access: yesFrontiers in Applied Mathematics and Statistics, 2023
This article deals with the numerical treatment of a singularly perturbed unsteady Burger-Huxley equation. The equation is linearized using the Newton-Raphson-Kantorovich approximation method.

A numerical algorithm for $L_2$ semi-discrete optimal transport in 3D [PDF]

open access: yes, 2014
This paper introduces a numerical algorithm to compute the $L_2$ optimal transport map between two measures $\mu$ and $\nu$, where $\mu$ derives from a density $\rho$ defined as a piecewise linear function (supported by a tetrahedral mesh), and where ...

The convergence theorem for fourth-order super-Halley method in weaker conditions

open access: yesJournal of Inequalities and Applications, 2016
In this paper, we establish the Newton-Kantorovich convergence theorem of a fourth-order super-Halley method under weaker conditions in Banach space, which is used to solve the nonlinear equations.

The Role of a Priori Estimates in the Method of Non-local Continuation of Solution by Parameter

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2020
An iterative method for continuation of solutions with respect to a parameter is proposed. The nonlocal case is studied when the parameter belongs to the segment of the real axis.

Nonlinear Systems of Volterra Equations with Piecewise Smooth Kernels: Numerical Solution and Application for Power Systems Operation

open access: yesMathematics, 2020
The evolutionary integral dynamical models of storage systems are addressed. Such models are based on systems of weakly regular nonlinear Volterra integral equations with piecewise smooth kernels. These equations can have non-unique solutions that depend
