On explosion time in stochastic differential equations driven by fractional Brownian motion

Johanna Garzon, Jorge A. Leon, Soledad Torres +2

In this article, we study the explosion time of the solution to autonomous stochastic differential equations driven by the fractional Brownian motion with Hurst parameter .…

Discretisation error for stochastic integrals with respect to the fractional Brownian motion with discontinuous integrands and local times

Valentin Garino, Lauri Viitasaari

We consider equidistant Riemann approximations of stochastic integrals with respect to the fractional Brownian motion with , where is an ar…

Geometric Characterization of the Eyring-Kramers Formula

Benny Avelin, Vesa Julin, Lauri Viitasaari

In this paper we consider the mean transition time of an over-damped Brownian particle between local minima of a smooth potential. When the minima and saddles are non-degenerate th…

Least squares estimator of fractional Ornstein Uhlenbeck processes with periodic mean

Salwa Bajja, Khalifa Es-Sebaiy, Lauri Viitasaari

We first study the drift parameter estimation of the fractional Ornstein-Uhlenbeck process (fOU) with periodic mean for every . More precisely, we extend the consi…

Asymptotic normality of randomized periodogram for estimating quadratic variation in mixed Brownian--fractional Brownian model

Ehsan Azmoodeh, Tommi Sottinen, Lauri Viitasaari

We study asymptotic normality of the randomized periodogram estimator of quadratic variation in the mixed Brownian--fractional Brownian model. In the semimartingale case, that is,…

Representation of stationary and stationary increment processes via Langevin equation and self-similar processes

Lauri Viitasaari

Let be a standard Brownian motion. It is well-known that the Langevin equation defines a stationary process called Ornstein-Uhlenbeck process. Furt…
