Pricing European Options under a Fuzzy Mixed Weighted Fractional Brownian Motion Model with Jumps

open access: yesFractal and Fractional, 2023
This study investigates the pricing formula for European options when the underlying asset follows a fuzzy mixed weighted fractional Brownian motion within a jump environment.

Deterministic Brownian motion [PDF]

open access: yesPhysical Review A, 1992
The goal of this thesis is to contribute to the ambitious program of the foundation of developing statistical physics using chaos. We build a deterministic model of Brownian motion and provide a microscpoic derivation of the Fokker-Planck equation.

Müntz linear transforms of Brownian motion [PDF]

open access: yes, 2014
We consider a class of Volterra linear transforms of Brownian motion associated to a sequence of Müntz Gaussian spaces and determine explicitly their kernels; the kernels take a simple form when expressed in terms of Müntz-Legendre polynomials. These are

Exact distributions of the maximum and range of random diffusivity processes

open access: yesNew Journal of Physics, 2021
We study the extremal properties of a stochastic process x _t defined by the Langevin equation ${\dot {x}}_{t}=\sqrt{2{D}_{t}}\enspace {\xi }_{t}$ , in which ξ _t is a Gaussian white noise with zero mean and D _t is a stochastic ‘diffusivity’, defined as

ON THE QHASI CLASS AND ITS EXTENSION TO SOME GAUSSIAN SHEETS

open access: yesInternational Journal for Computational Civil and Structural Engineering, 2022
Introduced in 2018 the generalized bifractional Brownian motion is considered as an element of the quasi-helix with approximately stationary increment class of real centered Gaussian processes conditioning by parameters.

On the Integral of the Fractional Brownian Motion and Some Pseudo-Fractional Gaussian Processes

open access: yesMathematics, 2019
We investigate the main statistical parameters of the integral over time of the fractional Brownian motion and of a kind of pseudo-fractional Gaussian process, obtained as a classical Gauss−Markov process from Doob representation by replacing ...

Functionals of exponential Brownian motion and divided differences [PDF]

open access: yes, 2011
We provide a surprising new application of classical approximation theory to a fundamental asset-pricing model of mathematical finance. Specifically, we calculate an analytic value for the correlation coefficient between exponential Brownian motion and ...
