S. V. Meleshko, S. Moyo G. F. Oguis

摘要:

本文给出了两个二阶常系数线性常微分方程组群分类的完备性。新的情况下,扩展了在文献中所做的。这些情况对应的类型的方程的系数矩阵的交换属性相对于因变量和一阶导数在所考虑的系统不成立。对所得结果进行了讨论,并给出了推广到含有两个以上方程的二阶常微分方程线性系的注记。

英文摘要:

The completeness of the group classification of systems of two linear second-order ordinary differential equations with constant coefficients is delineated in the paper. The new cases extend what has been done in the literature. These cases correspond to the type of equations where the commutative property of the coefficient matrices with respect to the dependent variables and the first-order derivatives in the considered system does not hold. A discussion of the results as well as a note on the extension to linear systems of second-order ordinary differential equations with more than two equations are given.
