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. |
