Starting from the 1-dimensional complex-valued Ornstein-Uhlenbeck process, we present two natural ways to imply the associated eigenfunctions of the 2-dimensional normal Ornstein-Uhlenbeck operators i...

We consider a reflected Ornstein-Uhlenbeck process driven by a fractional Brownian motion with Hurst parameter $H\in(0,1)$. Our goal is to estimate an unknown drift parameter $\alpha\in (-\infty,\inft...

We consider a transformed Ornstein-Uhlenbeck process model that can be a good candidate for modelling real-life processes characterized by a combination of time-reverting behaviour with heavy distribu...

Using Riemann-Stieltjes methods for integrators of bounded $p$-variation we define a pathwise integral driven by a fractional L\'{e}vy process (FLP). To explicitly solve general fractional stochastic ...

Sufficient conditions for equivalence of distributions in
LZ(O,T , H) of two Ornstein-Uhlenbeck processes taking values in
a Hilbert space H are given. The Girsanov theorem and some facts in

We prove the existence of an Omstein-Uhlenbeck type
process associated with the Evy Laplacian. Like the classical case, the
law of the Levy Brownian motion at time 1 is an invariant probability
of ...

2009/9/18
Several concrete parametric classes of tempered stable

In this paper, we investigate the consistency and asymptotic efficiency of an estimator of the drift matrix, $F$, of Ornstein-Uhlenbeck processes that are not necessarily stable. We consider all the c...
