Abstract
The “Skorokhod embedding” problem was solved for general strong Markov processes by Rost [R70,R71]: given such a process X = (X t; t ≥ 0), an initial law μ with σ-finite potential, and a target law v, there is a randomized stopping time T such that
if and only if the potential of μ dominates that of v. Subsequently various authors have shown that under additional hypotheses on X one can take T to be nonrandomized, i.e. a stopping time of the natural filtration of X. For recent work on this subject see [C85] and [FF90]; see also [Fa81,Fa83] which contain references for the earlier literature.
