As it was shown in [6], (1.1) does not possess an algebraic invariant, which is indicated by the simulations and visualizations of the orbits of this equation. See Figures 2.1–2.3. The rest of this section presents the basic results about Birkhoff normal forms and the KAM theory, see [9,11,20,21].

It is well known that algebraic theories are equivalent to finitary monads on $\\mathbf{Set}$. In this paper, we generalize this phenomenon to locally finitely presentable categories using …
WebIn 1927, G. D. Birkhoff wrote a remarkable treatise on the theory of dynamical systems that would inspire many later mathematicians to do great work. To a large extent, Birkhoff was writing about his own work on the subject, which was itself strongly influenced by Poincaré's approach to dynamical systems.
