Hopf bifurcations in resonance 2:1
Quoting from the paper's abstract: ``Hopf bifurcations for equations of control theory are studied in strong resonance case 2:1. The harmonic linearization approach and topological methods allow (us) to give the sharp analysis of the problem for the case of quadratic principal nonlinearity.''
