具有跳跃和不规则漂移的路径依赖偏微分方程的适定性和Dirichlet性质

Path-dependent SDEs with jumps and irregular drift: well-posedness and Dirichlet properties

Elena Bandini, Francesco Russo

摘要:

我们讨论了一个概念的路径依赖的分布漂移与可能的跳跃。我们解释它通过一个合适的鞅问题,我们提供的存在性和唯一性。相应的解决方案预计是狄利克雷过程,但我们给出的解决方案不满足这一属性的例子。在本文的第二部分中,我们确实状态和证明显着的新结果类的Dirichlet过程。

英文摘要:

We discuss a concept of path-dependent SDE with distributional drift with possible jumps. We interpret it via a suitable martingale problem, for which we provide existence and uniqueness. The corresponding solutions are expected to be Dirichlet processes, nevertheless we give examples of solutions which do not fulfill this property. In the second part of the paper we indeed state and prove significant new results on the class of Dirichlet processes.
