Nothing special, right? Hamiltonian-Hopf bifurcation or the Krein collision is a typical association. Nevertheless, practitioners in engineering and physics think differently. They discuss why multiple complex eigenvalues can be precursors of blackouts and why an eigenvalue that drifted towards a positive growth rate with the increase of the Reynolds number suddenly changes its trajectory and dives back to the left part of the complex plane. Why double coffee-filter makes the wine glass singing? How robust stability can occur at the Swallowtail? This and more in my talk (with the answers).
