G. Tscherne,W. Urdllutions with small amplitudes are unstable..When the Floquet exponents at criticality are complex and rationally independent of the fixed frequency, the solution of the spectral problem is quasi-periodic. The formal construction then gives the natural frequency of the bifurcating solution as a power
