    The author shows that any degree \(d\) deformation of a generic logarithmic polynomial differential equation with a persistent center must be logarithmic also, thus generalizing Ilyashenko's result on Hamiltonian equations. Some applications are also given. A hint towards studying some of the notions presented here to the case of an algebraically closed field instead of \(\mathbb {C}\) is also presented.
