Fluctuations in Systems with Multiple Steady States. Application to Lanchester Equations.
Abstract
We consider the effects of small random perturbations on deterministic systems of differential equations. The systems of interest have a steady state that is a saddle point. A first exit problem is formulated. The quantity of basic interest is the probability of exit from a band around the deterministic separatrix through a specified boundary, conditioned on initial position. A technique for the approximate calculation of this probability is given. As an example, we show how the theory applies to the calculation of the probability of victory in a combat that has a stochastic component. (Author)
