一次齐次位势的二阶可积性条件

Integrability conditions at order 2 for homogeneous potentials of degree -1

Thierry Combot

摘要:

证明了-1次亚纯齐次位势在位似轨道附近的一个2阶亚纯可积条件,推广了1阶Morales Ramis条件。反之,我们证明了如果满足这个准则,则二阶变分方程的Galois群是阿贝尔群,并明确地计算了伽罗瓦群和Picard-Vessiot扩张.

英文摘要:

We prove a meromorphic integrability condition at order 2 near a homothetic orbit for a meromorphic homogeneous potential of degree -1, which extend the Morales Ramis conditions of order 1. Conversely, we prove that if this criterion is satisfied, then the Galois group of second order variational equation is abelian and we compute explicitly the Galois group and the Picard-Vessiot extension.
