We study a class of singularly perturbed dynamical systems that have fast and slow components, 1 being the fast to slow timescale ratio. The fast components are governed by a strongly mixing discrete map, which is iterated at time intervals . The slow components are governed by a /rst-order /nite-di0erence equation that uses a time step . As tends to zero, the fast components may be eliminated,...
