与分数高斯噪声有关的分析和计算问题

Analytical and computational problems related to fractional Gaussian noise

Yuliya Mishura, Kostiantyn Ralchenko, René L. Schilling

摘要:

我们研究了分数高斯噪声的元素到其相邻元素的投影。我们证明了这种投影系数的一些解析结果,特别地,我们得到了它们的递推关系。我们还提出了一些关于这些系数的行为,提供数值证据支持这些abstutures,并研究它们在特定情况下的理论。作为一个独立的结果,我们研究了分数高斯噪声的协方差函数,证明了它对于$H>1/2$是完全单调的,特别是单调的,凸的,对数凸的以及其他有用的性质.

英文摘要:

We study the projection of an element of fractional Gaussian noise onto its neighbouring elements. We prove some analytic results for the coefficients of this projection, in particular, we obtain recurrence relations for them. We also make several conjectures concerning the behaviour of these coefficients, provide numerical evidence supporting these conjectures, and study them theoretically in particular cases. As an auxiliary result of independent interest, we investigate the covariance function of fractional Gaussian noise, prove that it is completely monotone for $H>1/2$, and, in particular monotone, convex, log-convex along with further useful properties.
