The multipliers of a fixed point of a piecewise-smooth, continuous map may change discontinuously as the fixed point crosses a discontinuity under smooth variation of parameters. We study the case wh...
The present paper is devoted to studying Hubbard's pendulum equation $\ddot{x} + 10^{-1} \dot{x} + \sin(x) = \cos(t)$. Using rigorous/interval methods of computation, the main assertion of Hubbard on...

We study global synchronization of coupled chaotic systems with random intermittent coupling. We use stochastic Lyapunov stability theory and partial averaging techniques to show that global synchronization is possible if the switching period is sufficiently small and if the oscillators globally synchronize under a time-averaged coupling. We study mean square and almost sure global synchronization, and we determine quantitative bounds for the exponential rate of decay of the synchronization error. We focus on master-slave synchronization, where two dynamical systems are coupled via a directed feedback that randomly switches among a finite set of given constant functions at a prescribed time rate. We apply the proposed approach to the synchronization of Chua circuits.
