Abstract
In this article we consider a Brownian motion with drift of the form with a specific nontrivial , predictable with respect to , the natural filtration of the Brownian motion . We construct a process , also predictable with respect to , such that is a Brownian motion in its own filtration. Furthermore, for any , we refine this construction such that the drift only takes values in , for fixed .
