Tsirel'son's example. This is a celebrated and mysterious example of a '1-dimensional' equation of type:
dX = dB + b(t,X.) dt, X(0)=0,
where b is a uniformly bounded previsible path functional. This equation automatically has a weak solution unique in law. For Tsirel'son's inspired choice of the functional b, X cannot be measurable on the filtration of B. This is an important counterexample in connection with the innovations problem in the theory of filtering.
