Gaussian and non-Gaussian processes of zero power variation
This paper considers the class of stochastic processes $X$ which are Volterra convolutions of a martingale $M$. When $M$ is Brownian motion, $X$ is Gaussian, and the... -
Functional limit theorems for generalized variations of the fractional Browni...
We prove functional central and non-central limit theorems for generalized variations of the anisotropic d-parameter fractional Brownian sheet (fBs) for any natural...
