Let Gamma be a compact Lie group and let Gamma(0) denote the connected component of the identity of Gamma. Suppose f is a map equivariant with respect to Gamma. We consider perturbations of f which are modelled by random compositions of equivariant maps which are close to f pointwise. We show that under mild assumptions on the distribution governing the choice of maps any invariant measure for the resulting Markov process is Gamma(0) invariant and absolutely continuous with respect to Lebesgue measure. Thus observations on the asymptotic dynamics of the perturbed system will have Gamma(0) symmetry.
