【Abstract】 This paper making use of stochastic Lyapundv functions and the exponential martingale inequality, resume[4],study property of the solution of a stochastic diffenrential equation driven by a nonlinear integrtor. We obtain upper estimates for the Lyapunov exponents of the semimartingale flows.更多还原
