摘要
基于Caputo变阶分数阶导数研究广义Birkhoff系统对称性的摄动与绝热不变量。作为特例,同时也讨论了变阶分数阶Birkhoff系统、分数阶广义Birkhoff系统及整数阶广义Birkhoff系统的绝热不变量。最后,举例说明结果的应用。
Based on the Caputo fractional order derivative of variable order,we have studied the perturbation to symmetry and the adiabatic invariant for the fractional generalized Birkhoffian system. As special cases,we have also discussed the adiabatic invariants for the fractional Birkhoffian system with variable order,the fractional generalized Birkhoffian system and the classical generalized Birkhoffian system. Finally,an example was given to illustrate the application of the methods and results.
