摘要

虽然分数布朗运动(FBm)具有非常有趣的特性,例如长距离依赖或自相似性,因此在电信或水文建模中被广泛利用,但它没有应用于数学金融,因为它不是半鞅,因此违反了无套利条件。尽管如此,我们还是用FBm作为积分器和非随机积分器来解释随机积分理论。

Stochastic Integration with Respect to Fractional Brownian Motion
While the Fractional Brownian Motion (FBm) has very interesting properties, such as long range dependency or self-­similarity, and is therefore widely exploited in telecommunication or hydrology modeling, it is not applied in mathematical finance because it is not a semi-martingale and violates thus the no arbitrage condition. We nonetheless explain the theory of stochastic integration with FBm as integrators and non stochastic integrands.
