Abstract
A stochastic process of Ornstein-Uhlenbeck type on the Euclidean space is a Markov process obtained from a spatially homogeneous Markov process undergoing a linear drift force determined by a matrix -Q. We give a criterion of recurrence and transience for a process of this type under the assumption that Q is diagonalizable and its eigenvalues are positive. No restriction is imposed on the part of the spatially homogeneous Markov process. Rigorous definition of our process is as follows. Let G be an operator defined by

The Generalized Hyperbolic Model: Estimation, Financial Derivatives, and Risk Measures

TL;DR: In this article, the authors describe more realistic models for financial assets based on generalized hyperbolic (GH) distributions and their subclasses, which allow for a natural definiton of volatility models by replacing the mixing generalized inverse Gaussian (GIG) distribution by appropriate volatility processes.

Hyperbolic Processes in Finance

TL;DR: In this article, Bamdorff-Nielsen and Shephard introduced the generalized hyperbolic stochastic volatility models, which is a class of distributions that is very often able to capture the distributions of financial data.

Some stationary processes in discrete and continuous time

TL;DR: In this paper, a number of stationary stochastic processes are presented with properties pertinent to modelling time series from turbulence and finance, such as log-linear tails and autocorrelation may have two or more time scales.

Random Fractals and Markov Processes

TL;DR: A survey on sample path properties of Markov processes, especially fractal properties of the random sets and measures determined by their sample paths, can be found in this paper, where the authors summarize recent results for Levy processes such as the Hausdorff and packing dimensions of their ranges, level sets, and multiple points; regularity properties of local times and self-intersection local times; multifractal analysis of the occupation measures and sample paths.

Liouville theorems for non-local operators

TL;DR: In this paper, the authors characterize some classes of pseudo-differential operators for which there are (or there are not) non-constant bounded harmonic functions and derive a probabilistic interpretation of the Liouville theorem by means of absorption functions for general Markov processes.

Operator-selfdecomposable distributions as limit distributions of processes of Ornstein-Uhlenbeck type

TL;DR: In this article, the class of limit distributions of Ornstein-Uhlenbeck processes on R d is characterized, and integro-differential equations for operator-self-decomposable distributions are established.

On a continuous analogue of the stochastic difference equation Xn=ρXn-1+Bn

TL;DR: The main analytical tool used to obtain these results is a theorem of Lukacs concerning characteristic functions of certain stochastic integrals as mentioned in this paper, and several other related results are obtained.

Langevins stochastic differential equation extended by a time-delayed term

TL;DR: The stochastic differential equation is a generalization of Langevin's equation as discussed by the authors, which is obtained if b = 0. Necessary and sufficient conditions on a, b and r are given under which a stationary so...
