摘要:
The large deviation principle obtained by Ventcel-Freidlin for the measures associated with time homogeneous Markov diffusions is extended to the measures given by non-homogeneous functional stochastic differential equations. The paper uses Keisler's infinitestimal technique for solving SDE's, together with a natural nonstrandard representation of action that simplifies calculations
