  • Remark concerning this paper when p < 2: if the generator does not depend on U (integrand in the integral w.r.t. the Poisson measure), our paper is safe. But if not, there is a mistake in the proof. Paper 15 gives the complete answer. Note that the conditions are quite different in this case (p<2) compared to p >=2.
  • The quasi left-continuity condition of the filtration can be removed (see the comments in Papers 13 and 15).
