摘要 考虑周期系统Laurent多项式型首次积分的不存在性.利用Floquet理论,证明了如果系统的特征乘数是-非共振的,则系统在平衡点附近不存在Laurent多项式型首次积分. We considered the nonexistence of Laurent polynomial first integrals for periodic system. Using the Floquet theory, we have proved that if the characteristic multipliers of the system are Z-independent, then the system does not have any nontrivial Laurent first integral in a neighborhood of a constant solution.
