Formal Paths, Iterated Integrals and the Center Problem for Ordinary Differential Equations
Abstract
Description
We continue the study of the center problem for the ordinary differential equation $v'=\sum_{i=1}^{\infty}a_{i}(x)v^{i+1}$ started in our earlier papers. In this paper we present the highlights of the algebraic theory of centers.
