Abstract

In this paper, we give the normal form of all planar polynomial vector fields of degree d 3 having two nonconcentric circles C-1 and C-2 as invariant algebraic curves and the function H=(C1C1 alpha)-C-beta with alpha and beta real values, as first integral. Moreover, we classify all global phase portraits on the Poincare disc of a subclass of these vector fields. (AU)
