N2 - © 2015, Allerton Press, Inc.Periodic perturbations of the oscillator $$\ddot x$$+ x3 + ax$$\dot x$$ = 0, a2 <8, are considered. Smallness of perturbations is governed by the smallness of the neighborhood of the state of equilibrium x = 0 and by a small positive parameter. Conditions are given that ensure that an invariant two-dimensional torus branches from the equilibrium when the small parameter passes through the zero value.
