Recently there has occurred a controversy between the semi-analytical prediction of linear stability of the soliton of the massive Gross–Neveu model and direct numerical observations of its instability for small values of the frequency. We revisit

We report a numerical observation that multiplicative random forcing (noise) significantly increases the probability of formation of extreme events in the one-dimensional, focusing nonlinear Schrodinger equation. Furthermore, this phenomenon is sensi

The Conjugate Gradient method (CGM) is known to be the fastest generic iterative method for solving linear systems with symmetric sign definite matrices. In this paper, we modify this method so that it could find fundamental solitary waves of nonline

We show that the equation governing pulse propagation in dispersion-managed optical fibers, as well as the reduced form of that equation, does not have conserved or periodically conserved quantities other than the mass, momentum, and (for the reduced

We develop a perturbation theory for the Benjamin-Ono (BO) equation. This perturbation theory is based on the inverse scattering transform for the BO equation, which was originally developed by Fokas and Ablowitz and recently refined by Kaup and Mats

We establish the functional relations between variations of the potential δu ( x ) in the scattering problem for the Lax operator of the Benjamin-Ono (BO) equation, on one hand, and the set of variations of the corresponding scattering data, on the

Numerical methods commonly used for solving ordinary differential equations, such as Euler and trapezoidal (both explicit and implicit), Runge–Kutta, and multistep methods are presented and compared with each other in terms of their accuracy and st
