带跳全耦合倒向随机微分方程的随机微分对策

Stochastic differential games for fully coupled FBSDEs with jumps

Juan Li, Qingmeng Wei

摘要:

研究了由布朗运动和泊松随机测度控制的完全耦合的正倒向随机微分方程(FBSDES)所定义的随机微分对策(SDG).对于SDG,上限值函数和下限值函数由具有跳变的受控全耦合FBSDE定义。利用文[6]中引入的一个新的变换,我们证明了上下值函数是确定的。然后,在建立了SDG上、低值函数的动态规划原理后,证明了SDG上、低值函数分别是相应的上、下Hamilton-Jacobi-Bellman-Isaacs(HJBI)方程的黏性解.进一步,在Isaacs条件下,对一种特殊情况($σ,\ h$不依赖于$y,\ z,\ k$),得到了对策值的存在性.

英文摘要:

This paper is concerned with stochastic differential games (SDGs) defined through fully coupled forward-backward stochastic differential equations (FBSDEs) which are governed by Brownian motion and Poisson random measure. For SDGs, the upper and the lower value functions are defined by the controlled fully coupled FBSDEs with jumps. Using a new transformation introduced in [6], we prove that the upper and the lower value functions are deterministic. Then, after establishing the dynamic programming principle for the upper and the lower value functions of this SDGs, we prove that the upper and the lower value functions are the viscosity solutions to the associated upper and the lower Hamilton-Jacobi-Bellman-Isaacs (HJBI) equations, respectively. Furthermore, for a special case (when $σ,\ h$ do not depend on $y,\ z,\ k$), under the Isaacs' condition, we get the existence of the value of the game.
