Ornstein–Uhlenbeck Process on Three-Dimensional Comb under Stochastic Resetting
Mathematics, 2023 The Ornstein–Uhlenbeck (O-U) process with resetting is considered as the anomalous transport taking place on a three-dimensional comb. The three-dimensional comb is a comb inside a comb structure, consisting of backbones and fingers in the following ...

Risks, 2022 In this study, we consider the pricing of energy derivatives when the evolution of spot prices follows a tempered stable or a CGMY-driven Ornstein–Uhlenbeck process.

European Journal of Mathematical Analysis, 2023 The paper estimates the Kolmogorov distance between the distribution of the normalized maximum likelihood estimator of the positive drift parameter in the nonergodic Ornstein-Uhlenbeck process and the standard Cauchy distribution and shows exponential ...

Symmetry of the isotropic Ornstein-Uhlenbeck process in a force field [PDF]
Open Communications in Nonlinear Mathematical Physics, 2021 We classify simple symmetries for an Ornstein-Uhlenbeck process, describing a particle in an external force field $f(x)$. It turns out that for sufficiently regular (in a sense to be defined) forces there are nontrivial symmetries only if $f(x)$ is at ...

Spurious ergodicity breaking in normal and fractional Ornstein–Uhlenbeck process
New Journal of Physics, 2020 The Ornstein–Uhlenbeck process is a stationary and ergodic Gaussian process, that is fully determined by its covariance function and mean. We show here that the generic definitions of the ensemble- and time-averaged mean squared displacements fail to ...

A construction of continuous-time ARMA models by iterations of Ornstein-Uhlenbeck processes [PDF]
, 2016 We present a construction of a family of continuous-time ARMA processes based on p iterations of the linear operator that maps a Lévy process onto an Ornstein-Uhlenbeck process. The construction resembles the procedure to build an AR(p) from an AR(1). We

Modern Stochastics: Theory and Applications, 2014 European call option issued on a bond governed by a modified geometric Ornstein-Uhlenbeck process, is investigated. Objective price of such option as a function of the mean and the variance of a geometric Ornstein-Uhlenbeck process is studied.

Estimating Drift Parameters in a Fractional Ornstein Uhlenbeck Process with Periodic Mean [PDF]
, 2015 We construct a least squares estimator for the drift parameters of a fractional Ornstein Uhlenbeck process with periodic mean function and long range dependence. For this estimator we prove consistency and asymptotic normality.
