| dc.description | Let G \subset \R^k be a convex polyhedral cone with vertex at the origin given as the intersection of half spaces {G_i, i= 1, ..., N}, where n_i and d_i denote the inward normal and direction of constraint associated with G_i, respectively. Stability properties of a class of diffusion processes, constrained to take values in G, are studied under the assumption that the Skorokhod problem defined by the data {(n_i, d_i), i = 1, ..., N} is well posed and the Skorokhod map is Lipschitz continuous. Explicit conditions on the drift coefficient, b(\cdot), of the diffusion process are given under which the constrained process is positive recurrent and has a unique invariant measure. Define \C \Df{- \sum_{i=1}^N α_i d_i; α_i \ge 0, i \in \{1, ..., N}}. Then the key condition for stability is that there exists δ\in (0, \infty) and a bounded subset A of G such that for all x \in G\backslash A, b(x) \in \C and \dist(b(x), \partial \C) \ge δ, where \partial \C denotes the boundary of \C. | |
