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.

Extended Newton–Kantorovich Theorem for Solving Nonlinear Equations

open access: yesFoundations, 2022
The Newton–Kantorovich theorem for solving Banach space-valued equations is a very important tool in nonlinear functional analysis. Several versions of this theorem have been given by Adley, Argyros, Ciarlet, Ezquerro, Kantorovich, Potra, Proinov, Wang, et al. This result, e.g., establishes the existence and uniqueness of the solution.

Minimal convex extensions and finite difference discretization of the quadratic Monge-Kantorovich problem [PDF]

open access: yes, 2018
We present an adaptation of the MA-LBR scheme to the Monge-Amp{\`e}re equation with second boundary value condition, provided the target is a convex set.

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 ...

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 ...

PROJECTION-ITERATION REALIZATION OF A NEWTON-LIKE METHOD FOR SOLVING NONLINEAR OPERATOR EQUATIONS

open access: yesJournal of Optimization, Differential Equations and Their Applications, 2019
We consider the problem of existence and location of a solution of a nonlinear operator equation with a Fr´echet differentiable operator in a Banach space and present the convergence results for a projection-iteration method based on a Newton-like method
