Title: Existence and Uniqueness of Stationary Distributions for Stochastic Delay Differential Equations with Positivity Constraints. 

Abstract: Deterministic dynamic models with delayed feedback and state constraints arise in a variety of applications in science and engineering.  There is interest in understanding what effect noise has on the behaviour of such models.  Here we consider a multidimensional stochastic delay differential equation with normal reflection as a noisy analogue of a deterministic system with delayed feedback and non-negativity constraints.  We obtain sufficient conditions for existence and uniqueness of stationary distributions for such equations.  The results are applied to an example from Internet rate control and a simple biochemical reaction system.
