随机线积分的非退化性

Non-degeneracy of Stochastic Line Integrals

Xi Geng, Sheng Wang

摘要:

给出了分数阶布朗运动驱动的亚椭圆型微分方程解的随机线积分和迭代线积分的密度存在性的定量判据.作为应用,我们还研究了这些粗糙微分方程的签名唯一性问题。

英文摘要:

We derive quantitative criteria for the existence of density for stochastic line integrals and iterated line integrals along solutions of hypoelliptic differential equations driven by fractional Brownian motion. As an application, we also study the signature uniqueness problem for these rough differential equations.
