  In this work, previous results concerning the infinitely many zeros of single
stochastic oscillators driven by random forces are extended to the general
class of coupled stochastic oscillators. We focus on three main subjects: 1)
the analysis of this oscillatory behavior for the case of coupled harmonic
oscillators; 2) the identification of some classes of coupled nonlinear
oscillators showing this oscillatory dynamics and 3) the capability of some
numerical integrators - thought as discrete dynamical systems - for reproducing
the infinitely many zeros of coupled harmonic oscillators driven by random
forces.
