二阶倒向偏微分方程的适定性

Wellposedness of Second Order Backward SDEs

H. Mete Soner, Nizar Touzi, Jianfeng Zhang

摘要:

我们提供了一个存在性和唯一性的理论向后的二阶偏微分方程的扩展。虽然标准的后向偏微分方程自然连接到半线性偏微分方程,我们的二阶扩展连接到完全非线性偏微分方程,特别是建议由Cheridito等人,我们提供了一个完全非线性扩展的费曼-卡茨公式。与早期的文件,本文的替代配方坚持认为,方程必须持有下的非支配家庭的相互奇异的概率测度。关键的论点是一个随机表示,建议由最优控制的解释,并在我们所附的文件分析

英文摘要:

We provide an existence and uniqueness theory for an extension of backward SDEs to the second order. While standard Backward SDEs are naturally connected to semilinear PDEs, our second order extension is connected to fully nonlinear PDEs, as suggested by Cheridito et.al. In particular, we provide a fully nonlinear extension of the Feynman-Kac formula. Unlike the earlier papers, the alternative formulation of this paper insists that the equation must hold under a non-dominated family of mutually singular probability measures. The key argument is a stochastic representation, suggested by the optimal control interpretation, and analyzed in our accompanying paper
