向前向后极小上解的稳定性和马尔可夫性

Stability and Markov Property of Forward Backward Minimal Supersolutions

Samuel Drapeau, Christoph Mainberger

摘要:

我们证明了在弱假设下,正倒向随机微分方程的最小上解相对于基本的正向过程的稳定性和局部性。前向过程出现在生成器和终端条件中。Painlevé-Kuratowski和凸上图收敛被用来建立稳定性。证明了马尔可夫正向过程的最小上解具有马尔可夫性。此外,它与一个时移问题有关,并被确定为相应偏微分方程的唯一最小粘性超解。

英文摘要:

We show stability and locality of the minimal supersolution of a forward backward stochastic differential equation with respect to the underlying forward process under weak assumptions on the generator. The forward process appears both in the generator and the terminal condition. Painlevé-Kuratowski and Convex Epi-convergence are used to establish the stability. For Markovian forward processes the minimal supersolution is shown to have the Markov property. Furthermore, it is related to a time-shifted problem and identified as the unique minimal viscosity supersolution of a corresponding PDE.
