The comonotone flow of a stochastically monotone Feller process on the real line

Abstract: We show that any stochastically monotone Feller semigroup on $\mathbb{R}$ can be extended by a consistent family of order-preserving Feller semigroups on the successive powers of $\mathbb{R}$. We exhibit a specific such family, which is uniquely characterized by a maximality property with respect to the super-modular order on $\mathbb{R}$^n.
