Geometric fractional Brownian motion model for commodity market simulation

open access: yesAlexandria Engineering Journal, 2021
The geometric Brownian motion (GBM) model is a mathematical model that has been used to model asset price paths. By incorporating Hurst parameter to GBM to characterize long-memory phenomenon, the geometric fractional Brownian motion (GFBM) model was ...

Stochastic optimal and time-optimal control studies for additional food provided prey–predator systems involving Holling type III functional response

open access: yesComputational and Mathematical Biophysics, 2023
This article consists of a detailed and novel stochastic optimal control analysis of a coupled non-linear dynamical system. The state equations are modelled as an additional food-provided prey–predator system with Holling type III functional response for

Exponential functionals of Brownian motion, II: Some related diffusion processes [PDF]

open access: yes, 2005
This is the second part of our survey on exponential functionals of Brownian motion. We focus on the applications of the results about the distributions of the exponential functionals, which have been discussed in the rst part.

Restrictions of Brownian motion [PDF]

open access: yes, 2014
Let $\{ B(t) \colon 0\leq t\leq 1\}$ be a linear Brownian motion and let $\dim$ denote the Hausdorff dimension. Let $\alpha>\frac12$ and $1\leq \beta \leq 2$.

Brownian Super-exponents [PDF]

open access: yes, 2006
We introduce a transform on the class of stochastic exponentials for d-dimensional Brownian motions. Each stochastic exponential generates another stochastic exponential under the transform.

Approximation of the Mean Escape Time for a Tilted Periodic Potential

open access: yesCommunications in Computational Physics, 2019
We present a formula approximating the mean escape time (MST) of a particle from a tilted multi-periodic potential well. The potential function consists of a weighted sum of a finite number of component functions, each of which is periodic.

A scaling proof for Walsh's Brownian motion extended arc-sine law [PDF]

open access: yes, 2012
We present a new proof of the extended arc-sine law related to Walsh's Brownian motion, known also as Brownian spider. The main argument mimics the scaling property used previously, in particular by D.

The moments of the area under reflected Brownian bridge conditional on its local time at zero

open access: yesInternational Journal of Stochastic Analysis, Volume 13, Issue 2, Page 99-124, 2000., 2000
This paper develops a recursion formula for the conditional moments of the area under the absolute value of Brownian bridge given the local time at 0. The method of power series leads to a Hermite equation for the generating function of the coefficients which is solved in terms of the parabolic cylinder functions.

Sojourn times for the Brownian motion

open access: yesInternational Journal of Stochastic Analysis, Volume 11, Issue 3, Page 231-246, 1998., 1998
In this paper explicit formulas are given for the distribution function, the density function and the moments of the sojourn time for the reflecting Brownian motion process.

Brownian local times

open access: yesInternational Journal of Stochastic Analysis, Volume 8, Issue 3, Page 209-232, 1995., 1995
In this paper explicit formulas are given for the distribution functions and the moments of the local times of the Brownian motion, the reflecting Brownian motion, the Brownian meander, the Brownian bridge, the reflecting Brownian bridge and the Brownian excursion.
