Abstract

Let over(z, ̇) = f (z) be an holomorphic differential equation having a center at p, and consider the following perturbation over(z, ̇) = f (z) + ε R (z, over(z, ̄)). We give an integral expression, similar to an Abelian integral, whose zeroes control the limit cycles that bifurcate from the periodic orbits of the period annulus of p. This expression is given in terms of the linearizing map of over(z, ̇) = f (z) at p. The result is applied to control the simultaneous bifurcation of limit cycles from the two period annuli of over(z, ̇) = i z + z2, after a polynomial perturbation. © 2007 Elsevier Inc.
