E\left[\int_0^tu \, dB_u \int_0^s u \, dB_u \right].
where B_u is the Brownian motion. Moreover, what the result when B_u is the fractional Brownian motion?

回帖推荐xuruilong100 发表于7楼 查看完整内容 使用Ito isometry的话积分针对同一个Bm,而不是B_u和B_v两个Bm。分数阶Ito isometry形式复杂,印象中好像是一个二重积分,外加几个奇怪的微分算子,不过具体到你这个问题就简单一些,因为被积分向使简单的确定性函数。fBm的文献中都应该有提到fractional Ito isometry,研究生论文写完之后就在没看过fBm,生疏了。

As we all know, fBm cannot be used in finance, because it produces arbitrage.Therefore, fBm in finance is forb
