Two-scale systems described
by singularly perturbed SDEs have been the subject of ample literature. However, this new
monograph develops subjects that were rarely addressed and could be given the
collective description "Stochastic Tikhonov-Levinson theory and its
applications." The book provides a mathematical apparatus designed to analyze the
dynamic behaviour of a randomly perturbed system with fast and slow variables. In contrast
to the deterministic Tikhonov-Levinson theory, the basic model is described in a more
realistic way by stochastic differential equations. This leads to a number of new
theoretical questions but simultaneously allows us to treat in a unified way a
surprisingly wide spectrum of applications like fast modulations, approximate filtering,
and stochastic approximation.
