Popis: We describe a form of piecewise deterministic dynamics, where solutions evolve deterministically throughout most of phase space, but, in the presence of noise, make nondeterministic jumps to other solutions when the trajectory passes near a singularity in the equations of motion. The type of singularity we consider in this paper is a single point where the Lipschitz conditions fail and many closed-loop trajectories share a common tangent point. It is shown that there is a finite uncertainty associated with the behaviour that is independent of the magnitude of the noise. The long-term behaviour, while similar in appearance to deterministic chaos, has rather different implications for prediction and control.
