分数布朗运动是可预测的吗?

Are fractional Brownian motions predictable?

Adam Jakubowski

摘要:

我们提供了一种设备,称为本地预测器,它扩展了可预测补偿器的思想。结果表明,当Hurst指数大于1/2时,fBm与其局部预报值相一致,而当Hurst指数小于1/2时,fBm不允许任何局部预报值.鞅(特别是:布朗运动)的局部预测平凡存在且等于0。

英文摘要:

We provide a device, called the local predictor, which extends the idea of the predictable compensator. It is shown that a fBm with the Hurst index greater than 1/2 coincides with its local predictor while fBm with the Hurst index smaller than 1/2 does not admit any local predictor. The local predictor of a martingale (in particular: Brownian motion) trivially exists and equals 0.
