简单阻尼谐振子的(1+1)Newton-Hooke群

(1+1) Newton-Hooke Group for the Simple and Damped Harmonic Oscillator

Przemyslaw Brzykcy

摘要:

证明了在轨道方法的框架下,简单谐振子和阻尼谐振子在抽象李代数的层次上是不可区分的。这为在轨道方法中处理耗散系统提供了可能性。深入分析了$(1+1)$维Newton-Hooke群的余伴随轨道。此外,有人认为,物理解释是进行了一个具体的实现李代数的光滑函数的相空间,而不是一个抽象的李代数。

英文摘要:

It is demonstrated that, in the framework of the orbit method, a simple and damped harmonic oscillators are indistinguishable at the level of an abstract Lie algebra. This opens a possibility for treating the dissipative systems within the orbit method. In depth analysis of the coadjoint orbits of the $(1+1)$ dimensional Newton-Hooke group are presented. Further, it is argued that the physical interpretation is carried by a specific realisation of the Lie algebra of smooth functions on a phase space rather than by an abstract Lie algebra.
