Central Limit Theorems for the Brownian motion on large unitary groups [PDF]

open access: yes, 2009
In this paper, we are concerned with the large N limit of linear combinations of the entries of a Brownian motion on the group of N by N unitary matrices. We prove that the process of such a linear combination converges to a Gaussian one.

Revisiting integral functionals of geometric Brownian motion

open access: yesStatistics & Probability Letters, 2020
In this paper we revisit the integral functional of geometric Brownian motion $I_t= \int_0^t e^{-( s + W_s)}ds$, where $ \in\mathbb{R}$, $ > 0$, and $(W_s )_s>0$ is a standard Brownian motion. Specifically, we calculate the Laplace transform in $t$ of the cumulative distribution function and of the probability density function of this ...

Which is the right option for Indian market: Gaussian, normal inverse Gaussian, or Tsallis?

open access: yesIIMB Management Review, 2019
This paper models Nifty spot prices using frameworks based on Gaussian distribution (geometric Brownian motion) and non-Gaussian distributions, viz. normal inverse Gaussian (NIG), and Tsallis distributions, to investigate which model best captures the ...

Option Pricing Based on Modified Advection-Dispersion Equation: Stochastic Representation and Applications

open access: yesDiscrete Dynamics in Nature and Society, 2020
In this paper, we first investigate the stochastic representation of the modified advection-dispersion equation, which is proved to be a subordinated stochastic process.

Geometric brownian motion: an alternative to high-frequency trading for small investors

open access: yesIndependent Journal of Management & Production, 2020
High-frequency trading (HFT) involves short-term, high-volume market operations to capture profits. To a large extent, these operations take advantage of early access to information using fast and sophisticated technological tools running on ...

Pricing European Vulnerable Options with Jumps and Stochastic Default Obstacles Barrier under Regime Switching

open access: yesMathematics, 2023
In this paper, we propose an enhanced model for pricing vulnerable options. Specifically, our model assumes that parameters such as interest rates, jump intensity, and asset value volatility are governed by an observable continuous-time finite-state ...

On the distribution of the time-integral of the geometric Brownian motion

open access: yesJournal of Computational and Applied Mathematics, 2022
We study the numerical evaluation of several functions appearing in the small time expansion of the distribution of the time-integral of the geometric Brownian motion as well as its joint distribution with the terminal value of the underlying Brownian motion.

Asian Option Pricing with Monotonous Transaction Costs under Fractional Brownian Motion

open access: yesJournal of Applied Mathematics, 2013
Geometric-average Asian option pricing model with monotonous transaction cost rate under fractional Brownian motion was established. The method of partial differential equations was used to solve this model and the analytical expressions of the Asian ...

MODELLING MALAYSIAN GOLD PRICES USING GEOMETRIC BROWNIAN MOTION MODEL

open access: yes, 2020
In this study, we use geometric Brownian motion, a mathematical model, to represent the future price path for Malaysian gold prices, namely Kijang Emas. We estimate the unknown parameters in the model, and we illustrate the accuracy of this method using ...
