球对称哈密顿系统零动量附近相对平衡的分岔

Bifurcations of relative equilibria near zero momentum in Hamiltonian systems with spherical symmetry

James Montaldi

摘要:

对于球对称的哈密顿系统,零动量和非零动量之间存在显著差异,在所有零动量的相对平衡中,零角速度和非零角速度的相对平衡之间存在显著差异。我们使用的技术从奇点理论研究家庭的相对平衡,出现作为一个对称的哈密顿量,它有一个组轨道的平衡与零动量扰动,使零动量的相对平衡不再平衡。我们还分析了这些扰动的相对平衡的稳定性,并考虑应用到卫星控制的转子。

英文摘要:

For Hamiltonian systems with spherical symmetry there is a marked difference between zero and non-zero momentum values, and amongst all relative equilibria with zero momentum there is a marked difference between those of zero and those of non-zero angular velocity. We use techniques from singularity theory to study the family of relative equilibria that arise as a symmetric Hamiltonian which has a group orbit of equilibria with zero momentum is perturbed so that the zero-momentum relative equilibrium are no longer equilibria. We also analyze the stability of these perturbed relative equilibria, and consider an application to satellites controlled by means of rotors.
