Brownian Motion on a Sphere: Distribution of Solid Angles

open access: yes, 2000
We study the diffusion of Brownian particles on the surface of a sphere and compute the distribution of solid angles enclosed by the diffusing particles.

On the expected uniform error of geometric Brownian motion approximated by the L\'evy-Ciesielski construction

open access: yes, 2017
It is known that the Brownian bridge or L\'evy-Ciesielski construction of Brownian paths almost surely converges uniformly to the true Brownian path. In the present article the focus is on the error.

Pricing of Proactive Hedging European Option with Dynamic Discrete Position Strategy

open access: yesDiscrete Dynamics in Nature and Society, 2019
Proactive hedging European option is an exotic option for hedgers in the options market proposed recently by Wang et al. It extends the classical European option by requiring option holders to continuously trade in underlying assets according to a ...

On the Probabilities of Correlated Defaults: a First Passage Time Approach

open access: yesNonlinear Analysis, 2008
This article investigates the joint probability of correlated defaults in the first passage time approach of credit risk subject to condition that the underlying firms’ assets values and the default boundaries follow geometric Brownian motion processes ...

Matrix valued Brownian motion and a paper by Polya [PDF]

open access: yesarXiv, 2008
We give a geometric description of the motion of eigenvalues of a Brownian motion with values in some matrix spaces. In the second part we consider a paper by Polya where he introduced a function close to the Riemann zeta function, which satisfies Riemann hypothesis.

A Hybrid Approach for Multiple Particle Tracking Microrheology

open access: yesInternational Journal of Advanced Robotic Systems, 2013
Geometric object detection has many applications, such as in tracking. Particle tracking microrheology is a technique for studying mechanical properties by accurately tracking the motion of the immersed particles undergoing Brownian motion.

Options Pricing with Arithmetic Brownian Motion and its Implication for Risk-Neutral Valuation [PDF]

open access: yes
Risk-neutral valuation is used widely in derivatives pricing. It is shown in this paper, however, that the naïve approach of simply setting the growth rate of the underlying security to risk-free interest rate, which happens to work for a geometric ...
