Existence and stability of solitons for fully discrete approximations of the nonlinear Schrödinger equation [PDF]

open access: yes, 2012
International audienceIn this paper we study the long time behavior of a discrete approximation in time and space of the cubic nonlinear Schrödinger equation on the real line.

On some one-step implicit methods as dynamical systems [PDF]

open access: yes, 2003
The one-step implicit methods, the backward Euler being the most known, require the solution of a nonlinear equation at each step.To avoid this, these methods can be approximated by making use of a one step of a Newton method.

\^A-and \^I-stability of collocation Runge-Kutta methods

open access: yes, 2023
This paper deals with stability of classical Runge-Kutta collocation methods. When such methods are embedded in linearly implicit methods as developed in [12] and used in [13] for the time integration of nonlinear evolution PDEs, the stability of these ...

On the convergence of a method for solving two point boundary value problems by optimal control [PDF]

open access: yes, 2002
Using the idea of the least squares method, a nonlinear two point boundary value problem is transformed into an optimal control problem. For solving the optimal control problem the gradient method is used.

Functions with bounded E-d-variation on undirected tree networks [PDF]

open access: yes, 2002
In this paper we define and study functions with bounded \(E-d\)-variation on undirected tree networks. For these functions with bounded \(E-d\)-variation we establish a Jordan type theorem.
