具有零次齐次位势的自然哈密顿系统的可积性

Integrability of natural Hamiltonian systems with homogeneous potentials of degree zero

Guy Casale, Guillaume Duval, Andrzej J. Maciejewski, Maria Przybylska

摘要:

本文导出了具有零次齐次位势的自然哈密顿系统在Liouville意义下可积的必要条件。我们得到这些条件通过分析的微分伽罗瓦群的变分方程沿一个特解所产生的非零解$\vd\in\C^n$的非线性方程$\grad V(\vd)=\vd$。证明了若系统可积,则黑塞矩阵$V''(\vd)$只有整数特征值,是半单的.

英文摘要:

We derive necessary conditions for integrability in the Liouville sense of natural Hamiltonian systems with homogeneous potential of degree zero. We derive these conditions through an analysis of the differential Galois group of variational equations along a particular solution generated by a non-zero solution $\vd\in\C^n$ of nonlinear equations $\grad V(\vd)=\vd$. We proved that if the system integrable then the Hessian matrix $V''(\vd)$ has only integer eigenvalues and is semi-simple.
