Stuart-Landau Oscillator: Variations on a themeAbstract
The two-dimensional Stuart-Landau system is a paradigmatic model of nonlinear oscillator that exhibits Hopf bifurcation. We propose a generalisation to arbitrary dimensions, retaining its essential features, including exact solvability. We shall discuss the asymptotic behaviour of possible trajectories, limit cycles and basins of attraction. Modulation of its parameters, the dynamics of coupled oscillators and an ultrametric analogue will be commented upon.
