平均场型二次倒向随机微分方程

Mean-field type Quadratic BSDEs

Hélène Hibon, Ying Hu, Shanjian Tang

摘要:

本文给出了生成元也依赖于两个变量的均值的二次B超可解性的几个新结果。首先,我们考虑这样的BMO鞅的John-Nirenberg不等式估计它的第一个未知变量的发展的贡献。然后,我们考虑具有一个加法期望值的二次生成元除了通常的二次之一的Battlefield。在这种情况下,我们使用一个确定性的推移变换的第一个未知变量,当通常的二次生成既不依赖于第一个变量,也不依赖于其平均值,一般情况下,可以处理的不动点参数。

英文摘要:

In this paper, we give several new results on solvability of a quadratic BSDE whose generator depends also on the mean of both variables. First, we consider such a BSDE using John-Nirenberg's inequality for BMO martingales to estimate its contribution to the evolution of the first unknown variable. Then we consider the BSDE having an additive expected value of a quadratic generator in addition to the usual quadratic one. In this case, we use a deterministic shift transformation to the first unknown variable, when the usual quadratic generator depends neither on the first variable nor its mean, the general case can be treated by a fixed point argument.
