论整环上随机微分对策值函数的正则性与逼近

On regularity properties and approximations of value functions for stochastic differential games in domains

N. V. Krylov

摘要:

证明了对于任意常数$K\geq1$,时间齐次随机微分对策在整个空间上的值函数可以用二阶导数以常数乘以$K$为界的值函数逼近到$K$上的常数.在证明这一结果的过程中,我们证明了整环上和全空间上的随机微分对策的值函数在各种情况下都允许Lipschitz常数的估计。

英文摘要:

We prove that for any constant $K\geq1$, the value functions for time homogeneous stochastic differential games in the whole space can be approximated up to a constant over $K$ by value functions whose second-order derivatives are bounded by a constant times $K$. On the way of proving this result we prove that the value functions for stochastic differential games in domains and in the whole space admit estimates of their Lipschitz constants in a variety of settings.
