A Package for Generating the Determining System of Nonclassical Symmetry of Differential Euations(English)
-
摘要: 给出了计算微分方程非经典对称决定方程组的一个算法.基于此算法,在 Maple系统上给出一个实现:NGDS.并举例说明了此软件包的有效性.Abstract: An algorithm for calculating the determining euations associated with non-classical method of symmetry reductions for system of partial differential euations (PDEs) is described.Based on this algorithm, an implementation bf NGDS on Maple for generating the determining euations for Lie non-classical symmetry groups of differential euation(s) is presented, and an example is illustrated the correctness and effectiveness of our package bf NGDS.
