摘要
我们考虑可测函数 ,其中对于任意 , 属于(关于 Lévy 过程的)Malliavin Sobolev 空间 ,并给出关于 和 的充分条件,使得 。上述结果被应用于证明由 Lévy 噪声驱动的 BSDE(倒向随机微分方程)解的 Malliavin 可导性,其中生成元由循序可测函数 给出。

41 pages. In Theorem 3.12 (iii) and Assumption ($A_f$) e) the local Lipschitz condition on the Malliavin derivative of the generator has been weakened by introducing a map $\rho$ which determines the degree of a function's uniform continuity. One step in the proof of Theorem 3.12 has been corrected assuming slightly stronger integrability conditions in the assumptions of the Theorem
