Thursday, February 22nd Vladimir Semenov (Saratov State University) Bifurcations without parameters in memristor-based oscillators with lines of equilibria
Various models of memristor-based Chua's oscillator are discussed in the context of bifurcations without parameters. The studied oscillators have one thing in common: they have infinitely many equilibrium points, which build lines of equilibria. A list of revealed bifurcations includes the Hopf bifurcation and the period-doubling bifurcation affecting the periodic solutions, as well as the pitchfork, transcritical and saddle-node bifurcations of steady states. In addition, the issues concerning physical realization of the dynamics of systems with a line of equilibria are also analysed.

The meeting will take place via Zoom and start at 15:15
