Tempered fractional Brownian motion
Tempered fractional calculus
Abstract 1: Tempered fractional Brownian motion (TFBM) modifies the power law kernel in the moving
average representation of a fractional Brownian motion, adding an exponential tempering.
Tempered fractional Gaussian noise (TFGN), the increments of TFBM, form a stationary time
series that can exhibit semi-long range dependence. This paper develops the basic theory
of TFBM, including moving average and spectral representations, sample path properties,
and an application to modeling wind speed.
Abstract 2: Tempered fractional integral (TFI) is a bounded linear operator and keeps the spaces Lp(R) invariant. The stochastic integral of deterministic functions
with respect to tempered fractional Brownian motion (TFBM) will be investigated. As a consequence , the Mat.ern covariance function will be shown as a tempered fractional integral of white noise.
