Perturbation Theory for Integrable Systems,s around the Sun can be regarded as a perturbation of the integrable problem of the motion of noninteracting point masses around a fixed center of attraction. Methods for studying such systems have been developed, which form what is known as . These methods are usually simple and effective. They oftCRACY 发表于 2025-3-23 20:23:46

Theory of Small Oscillations,earized system can be integrated. After this is done, the main properties of the oscillations in the original system can frequently be determined using the theory of normal forms of Poincare-Birkhoff. This theory is an analog of perturbation theory (Ch. 5, §2). Here the linearized system plays the r初学者 发表于 2025-3-24 06:06:11
