On 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 behavior 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… Show more

“…Hence, the action of L(t ) is termed reflection at the boundary of the orthant n + . Further, the regulator L(t ) satisfies the following properties (see also Harrison [4] ): We will refer to Definition 2.1.1 of Kinnally and Williams [6] for the definition of solution to equation (4). For the existence and uniqueness of the solution we shall impose the following hypothesis:…”

“…In particular, due to properties (L1) and (L2), (X (t ), L(t )) is a solution to the Skorokhod problem for S(X ). Using the form of solution to Skorokhod problem, there exist Lipschitz functions φ with Lip-coefficient k φ > 0 and ψ with Lip-coefficient k ψ > 0 (under the sup-norm, see Appendix A of [6] ) such that…”

“…This can be obtained in the following customary way: Set Z(t) = x(0) + It is known (see e.g. [8,13]) that we have an explicit formula for the regulator term Y in terms of Z, the so-called reflector term: for each i = 1, . .…”
