摘要:

该文利用半序理论和随机压缩映象原理, 得到了一类不连续随机增算子随机不动点的唯一存在定理. 作为应用,考虑了Rn中含间断项的一阶随机微分积分方程初值问题.

关键词: 不连续随机算子, 随机压缩映象原理, 随机不动点, 随机微分积分方程

Abstract:

By using the order theory and random contracted mapping theorem, the existence and uniqueness of random fixed point for a class of discontinuous random operators is obtained. As an application, the  existence of the random solution for the initial value problem of the random differential and integral equations in Rn is established.

Key words: Discontinuous random operator, Random contracting mapping theorem, Random fixed points, Random differentiation and integration equations
