Abstract:
For differential equations of the form $x'=\varepsilon f(t,x;\varepsilon)$ in a Banach space a modification of the classical Krylov-Bogolyubov method is put forward. It allows complications in the construction of
higher-order approximations which stem from the ‘small denominators problem’ to be avoided and
many of the standard constraints on the behaviour of the function $f$ to be eliminated. The approach suggested is based on some results on the Fourier transforms of distributions.
Bibliography: 17 titles.
Keywords:
method of averaging, spectrum, distributions, Fourier transform.
