Geometric fractional Brownian motion model for commodity market simulation
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 ...

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

Square variation of Brownian paths in Banach spaces
It is known that if {W(t), 0 ≤ t ≤ 1} is a standard Brownian motion in ℝ then almost surely. We generalize this celebrated theorem of Levy to Brownian motion in real separable Banach spaces.

A note on local asymptotic behaviour for Brownian motion in Banach spaces
In this paper we obtain an integral characterization of a two‐sided upper function for Brownian motion in a real separable Banach space. This characterization generalizes that of Jain and Taylor [2] where B = ℝn. The integral test obtained involves the index of a mean zero Gaussian measure on the Banach space, which is due to Kuelbs [3].

Macroscopic limit of a Fokker-Planck model of swarming rigid bodies
We consider self-propelled rigid bodies interacting through local body-attitude alignment modelled by stochastic differential equations. We derive a hydrodynamic model of this system at large spatio-temporal scales and particle numbers in any dimension

Infectious illnesses like hepatitis place a heavy cost on global health, and precise mathematical models must be created in order to understand and manage them.
