摘要
本文用随机Lypunov函数和指数鞅不等式研究由非线性积分驱动的随机微分方程定义的半鞅流的性质,得出流的Lyspunov指数的估计式。
This paper,making use of stochastic Lyapunov functions and the exponntial martingale inequality,Studies property of the solution Of a stochastic diffenrential equation driven by a nonlinear integrator. we obtain upper estimates for the Lyapunov exponents of the semimartingale flows.
