چکیده

We review the probabilistic properties of Ornstein-Uhlenbeck processes in Hilbert spaces driven by Lévy processes. The emphasis is on the different contexts in which these processes arise, such as stochastic partial differential equations, continuous-state branching processes, generalised Mehler semigroups and operator self-decomposable distributions. We also examine generalisations to the case where the driving noise is cylindrical. MSC 2010 subject classifications: Primary 60G51; secondary 60H15, 60H10, 60E07, 60J80.

Method of Moments Estimation of Ornstein-Uhlenbeck Processes Driven by General Lévy Process

Ornstein-Uhlenbeck processes driven by general Lévy process are considered in this paper. We derive strongly consistent estimators for the moments of the underlying Lévy process and for the mean reverting parameter of the Ornstein-Uhlenbeck process. Moreover, we prove that the estimators are asymptotically normal. Finally, we test the empirical performance of our estimators in a simulation stud...

On exit times of Lévy-driven Ornstein–Uhlenbeck processes

We prove two martingale identities which involve exit times of Lévy-driven Ornstein–Uhlenbeck processes. Using these identities we find an explicit formula for the Laplace transform of the exit time under the assumption that positive jumps of the Lévy process are exponentially distributed.

Prediction of fractional convoluted Lévy processes with application to credit risk

Fractional convoluted Lévy processes (fcLps) are introduced by a multivariate componentwise Molchan-Gosolov transformation based on an n-dimensional driving Lévy process. Using results of fractional calculus and infinitely divisible distributions we are able to calculate the conditional characteristic function of integrals driven by fcLps. This leads to important prediction results including th...

Ornstein–Uhlenbeck related models driven by Lévy processes

Recently, there has been increasing interest in continuous-time stochastic models with jumps, a class of models which has applications in the fields of finance, insurance mathematics and storage theory, to name just a few. In this chapter we shall collect known results about a prominent class of these continuoustime models with jumps, namely the class of Lévy-driven Ornstein–Uhlenbeck processes...

Parameter Estimation for Ornstein-uhlenbeck Processes Driven by Α-stable Lévy Motions

The parameter estimation theory for stochastic differential equations driven by Brownian motions or general Lévy processes with finite second moments has been well developed. In this paper, we consider the parameter estimation problem for Ornstein-Uhlenbeck processes driven by α-stable Lévy motions. The classical maximum likelihood method does not apply in this context because the likelihood ra...
