چکیده
A set of Maple V R.3/4 computer algebra routines for the analytical solving of 1 order ODEs, using Lie group symmetry methods, is presented. The set of commands includes a 1 order ODEsolver and routines for, among other things: the explicit determination of the coefficients of the infinitesimal symmetry generator; the construction of the most general invariant 1 order ODE under given symmetries; the determination of the canonical coordinates of the underlying invariant group; and the testing of the returned results.

متن کاملODE trends in computer algebra: Four linear and nonlinear challenges
This paper discusses possible solving strategies regarding four ODE problems, all relevant and currently out of the scope of the Maple ODE solver. The problems are: 1. Transformations linearizing non-linear first order ODEs 2. Non-linear 2nd order ODEs for which point symmetries are of no use 3. Hypergeometric solutions for 2nd order linear ODEs 4. Solutions for third and higher order linear OD...
متن کاملThe smoothed particle hydrodynamics method for solving generalized variable coefficient Schrodinger equation and Schrodinger-Boussinesq system
A meshless numerical technique is proposed for solving the generalized variable coefficient Schrodinger equation and Schrodinger-Boussinesq system with electromagnetic fields. The employed meshless technique is based on a generalized smoothed particle hydrodynamics (SPH) approach. The spatial direction has been discretized with the generalized SPH technique. Thus, we obtain a system of ordinary...
متن کاملSymmetry Classification of First Integrals for Scalar Linearizable Second-Order ODEs
Symmetries of the fundamental first integrals for scalar second-order ordinary differential equations ODEs which are linear or linearizable by point transformations have already been obtained. Firstly we show how one can determine the relationship between the symmetries and the first integrals of linear or linearizable scalar ODEs of order two. Secondly, a complete classification of point symme...

An algorithm for solving first order ODEs, by systematically determining symmetries of the form [ξ = F (x), η = P (x) y+Q(x)] where ξ ∂/∂x+η ∂/∂y is the symmetry generator is presented. To these linear symmetries one can associate an ODE class which embraces all first order ODEs mappable into separable through linear transformations {t = f(x), u = p(x) y + q(x)}. This single ODE class includes ...
