Abstract
New cases of integrable ninth-order dynamical systems that are homogeneous in terms of some of their variables are presented, in which a system on the tangent bundle of a four-dimensional manifold can be distinguished. In this case, the force field is divided into an internal (conservative) and an external one, which has dissipation of different signs. The external field is introduced using some unimodular transformation, and it generalizes previously considered fields. Complete sets of both first integrals and invariant differential forms are given.
可积分九阶保守和耗散动力系统的新案例
摘要 介绍了可积分九阶动力系统的新情况，这些系统的某些变量是同质的，其中可以区分四维流形切线束上的系统。在这种情况下，力场分为内部力场（保守力场）和外部力场，后者具有不同符号的耗散。外部力场是通过某种单模态变换引入的，它概括了之前考虑过的力场。给出了第一积分和不变微分形式的完整集合。
