Abstract:
We propose a constructive form of the Newton–Kantorovich method to obtain solutions for evolutionary equations with small nonlinearities. The construction is applicable to equations in non-Banach linear spaces. The paper presents only a sketch of the method, without specifying the norms involved and without giving necessary $\varepsilon $–$\delta $ details.
Keywords:evolutionary equations, Newton–Kantorovich scheme, KAM theory, approximate propagators.
