Representation of self-similar Gaussian processes [PDF]

open access: yes, 2014
We develop the canonical Volterra representation for a self-similar Gaussian process by using the Lamperti transformation of the corresponding stationary Gaussian process, where this latter one admits a canonical integral representation under the ...

Necessary and sufficient condition for the smoothness of intersection local time of subfractional Brownian motions

open access: yes, 2011
Let SH and S̃H be two independent d-dimensional sub-fractional Brownian motions with indices H ∈ (0, 1). Assume d ≥ 2, we investigate the intersection local time of subfractional Brownian motions ℓT=∫0T∫0TδStH-S̃sHdsdt,T>0, where δ denotes the Dirac ...

Towards the Modeling of Neuronal Firing by Gaussian Processes [PDF]

open access: yes, 2003
This paper focuses on the outline of some computational methods for the approximate solution of the integral equations for the neuronal firing probability density and an algorithm for the generation of sample-paths in order to construct histograms ...

The Multiparameter Fractional Brownian Motion

open access: yes, 2006
We define and study the multiparameter fractional Brownian motion. This process is a generalization of both the classical fractional Brownian motion and the multiparameter Brownian motion, when the condition of independence is relaxed. Relations with the
