An improvement of the product integration method for a weakly singular Hammerstein equation

, 2016
We present a new method to solve nonlinear Hammerstein equations with weakly singular kernels. The process to approximate the solution, followed usually, consists in adapting the discretization scheme from the linear case in order to obtain a nonlinear ...

A Newton–Kantorovich theorem for equations involving m-Fréchet differentiable operators and applications in radiative transfer

Journal of Computational and Applied Mathematics, 2001
The author studies the problem of approximating a locally unique solution of a nonlinear operator equation \( F(x)=0\), where \(F\) is an \(m\)-times Fréchet-differentiable operator (\(m \geq 2\) is a positive integer) defined on a convex subset \(D\) of a Banach space \(E_1\) with values in a Banach space \(E_2\).

On the numerical calculation of the roots of special functions satisfying second order ordinary differential equations

, 2015
We describe a method for calculating the roots of special functions satisfying second order linear ordinary differential equations. It exploits the recent observation that the solutions of a large class of such equations can be represented via ...

A new approach to improve ill-conditioned parabolic optimal control problem via time domain decomposition

, 2015
In this paper we present a new steepest-descent type algorithm for convex optimization problems. Our algorithm pieces the unknown into sub-blocs of unknowns and considers a partial optimization over each sub-bloc.
