On the center problem for ordinary differential equations

Abstract: We study the moments finiteness problem for the class of Lipschitz maps F : [a, b] → R n with images in a compact Lipschitz triangulable curve Γ. We apply the obtained results to the center problem for ODEs describing in some cases (including equations with analytic coefficients) the set of universal centers of such equations by vanishing of finitely many moments from their coefficients.

“…Although the Center and the Hilbert problems for equation (C) on an interval (or in general on a non-closed curve) do not correspond directly to the classical setting, they presents an interest by their own and they have been intensively investigated in [3][4][5][19][20][21][22]25,36,37,54,58] and in many other publications. It is a general belief that the Center and Hilbert problems for a polynomial Abel equation (C) on the interval present all the main difficulties of the classical ones while possibly simplifying essential technical details.…”
