Lyapunov quantities in the problem about local bifurcations of non-autonomous periodic dynamical systems (Q2211412)

This short and concise, but very interesting, paper deals with non-autonomous parametric differential systems with periodic right-hand side. The main goal is to give a brief investigation of local bifurcation scenarios for Andronov-Hopf bifurcations and the forced oscillations. This paper derives formulas for the bifurcation and for the calculation of Lyapunov quantities.
