摘要
本文利用弱连续随机算子的 Darbo 型不动点定理,得到 Banach 空间中随机微分方程弱解的存在性。
This paper first obtains a random Darbo's fixed point theorem by a general random fixed point theo- rem for weak continuous random operators.Then using this result gives some existence theorem for weak solutions of random differential equations in Banach spaces,which improves some main results in[3—5]
