Abstract
We present a version of the Wentzell-Freidlin theory for Markov chains which includes random perturbations not only of deterministic motions but also of Markov chains. Some results for the continuous-time case are obtained as corollaries. In particular, by this method one can treat random perturbations of degenerate diffusions even when the large deviations principle fails.
