2724 CHAPTER 79. INCLUDING STOCHASTIC INTEGRALS

where V ⊆W,W ′ ⊆ V ′ and B ∈ L (W,W ′) being self adjoint and one to one by using amore technical Ito formula. However, this has not been done. A non probabilitic versionis in [85]. I don’t know how to resolve the problem in which B is only nonnegative. Goodresults are certainly available in the non probabilistic setting without the stochastic integral.Some were presented earlier.
