Query: Multidimensional stochastic differential equations with distributional
  drift   This paper investigates a time-dependent multidimensional stochastic
differential equation with drift being a distribution in a suitable class of
Sobolev spaces with negative derivation order. This is done through a careful
analysis of the corresponding Kolmogorov equation whose coefficient is a
distribution.
