A Wong-Zakai theorem for SDEs with singular drift

We study stochastic differential equations (SDEs) with multiplicative Stratonovich-type noise of the formdXt=b(Xt)dt+σ(Xt)∘dWt,X0=x0∈Rd,t⩾0, a possibly singular drift b∈Lp(Rd), p>d and p⩾2, show that such SDEs can be approximated by random ordinary smoothing at same time. further prove support theorem for this class in rather simple way using Girsanov theorem.
