A classification of center-foci

Roger McCann

Vol. 32 (1970), No. 2, 467–478
Abstract

The main purpose of this paper is to classify center-foci according to isomorphisms. Necessary and sufficient conditions are found for an isomorphism to exist in terms of properties on the cycles in suitable neighborhoods of the center-foci. In the last section 0+ stable isolated critical points are classified according to isomorphisms.
