摘要: 利用停线给出两指标强鞅停止的定义. 通过研究两指标强鞅的停止性质, 得到强鞅的停止仍是强鞅、 平方可积强鞅的停止仍是平方可积强鞅、一致可积强鞅的停止仍是一致可积强鞅等主要结果.

关键词: 强鞅, 停止, 性质

Abstract: The present paper presents the definition of the stopping for two-parameter strong martingale and deals with the stopping properties for two-parameter strong martingale. It has been proved that the stopping for strong martingale is still strong martingale, the stopping for square integrable strong martingale is still square integrable strong martingale, the stopping for uniform integrable martingale is still uniform integrable strong martingale.

Key words: strong martingale, stopping, property
