一种新的适合于概率测度变化的严格局部鞅的滤波增广

A new kind of augmentation of filtrations suitable for a change of probability measure by a strict local martingale

Doerte Kreher, Ashkan Nikeghbali

摘要:

本文引入了一类新的沿停时序列的滤波增广。这种增广适用于构造与正严格局部鞅相关的新的概率测度,如在\cite{split1}中所做的那样,而另一方面,它又足够丰富,使随机分析的经典结果在某些随机区间上成立。

英文摘要:

In this note we introduce a new kind of augmentation of filtrations along a sequence of stopping times. This augmentation is suitable for the construction of new probability measures associated to a positive strict local martingale as done in \cite{split1}, while it is on the other hand rich enough to make classical results from stochastic analysis hold true on some stochastic interval of interest.
