UNIQUENESS OF SOLUTIONS TO SDES DRIVEN BY SEMIMARTINGALE WITH NON-LIPSCHITZ CONDITIONS
【摘要】 本文研究了非Lipschitz条件下半鞅随机微分方程.利用Itö分析和Gronwall不等式,探讨了随机微分方程无爆炸解,并证明了随机微分方程解的唯一性.
【Abstract】 In this article,a class of stochastic differential equations(SDEs) driven by semi-martingale with non-Lipschitz coefficients is studied.By using Ito calculus and Gronwall inequality, no explosion on the solution of SDEs is investigated.A pathwise uniqueness of solutions is proved.
