Numerical Simulation Results Of Spatial Optical Soliton Formation In Using this computational method, we demonstrate the existence of two different solitons in optical media described by the self focusing cubic and the self defocusing quintic nonlinear. In the present paper several practical aspects of the application of the fourier transform based pseudospectral method for the numerical integration of equations of different types are discussed and several examples of applications of the discrete spectral analysis are introduced.

From pde class we know that this is a symmetric positive semidefinite (spsd) diferential operator with only constant functions in its null space; proving this uses integration by parts. when discretized, this will become a matrix l. we want this matrix to be spsd with only e in its null space.

The method is based on the explicit analytical integration of the linear part of the equation, through an integrating factor. the idea of exactly integrating a sti linear part has been developed before in various contexts. Pseudospectral methods are based on discrete function approximations that allow exact interpolation at so called collocation points. the most prominent examples are the fourier method based on trigonometric basis functions and the chebyshev method based on chebyshev polynomials. We report on a solver for the three‐dimensional two‐fluid plasma model equations. this solver is particularly suited for simulating the interaction between short laser pulses with plasmas. The ps method then becomes particularly easy to apply to equations with variable coefficients and nonlinearities, since these give rise only to products of numbers (rather than to problems of determining the expansion coefficients for products of expansions).
