摘要
It is proved that a periodically forced second-order equation with a singular nonlinearity in the origin with linear growth in infinity possesses a T-periodic stable solution for high values of the mean value of the forcing term. The method of proof combines a rescaling argument with the analysis of the first twist coefficient of the Birkhoff normal form for the Poincare map.
