Number of paths versus number of basis functions in American option pricing

open access: yes, 2003
An American option grants the holder the right to select the time at which to exercise the option, so pricing an American option entails solving an optimal stopping problem.

A SHARP MAXIMAL INEQUALITY FOR A GEOMETRIC BROWNIAN MOTION [PDF]

open access: yesTaiwanese Journal of Mathematics, 2015
Let $X=(X_t)_{t\geq0}$ be a geometric Brownian motion with drift $\mu$ and volatility $\sigma>0$, and let $Y=(Y_t)_{t\geq0}$ be the associated maximum process of $X$. Under certain conditions, we prove a sharp maximal inequality for the geometric Brownian motion.

Light‐Fueled In‐Operando Shape Reconfiguration, Fixation, and Recovery of Magnetically Actuated Microtextured Covalent Adaptable Networks

open access: yesAdvanced Materials, EarlyView.
A covalent adaptable network with dynamic disulfide bonds (DS‐CAN) can rearrange its molecular topology through heating or UV irradiation. When combined with ferromagnetic particles, its photoresponsiveness at room temperature enables contactless, spatiotemporal regulation of dynamic bond exchanges during magnetomechanical actuation.

Application of the Fractal Brownian Motion to the Athens Stock Exchange

open access: yesFractal and Fractional
The Athens Stock Exchange (ASE) is a dynamic financial market with complex interactions and inherent volatility. Traditional models often fall short in capturing the intricate dependencies and long memory effects observed in real-world financial data. In

Interfacial Yield Stress Response in Synthetic Mucin Solutions

open access: yesAdvanced Materials Interfaces, EarlyView.
The solution rheology of novel synthetic mucins mimicking natural mucin domains is studied. Like many natural mucin solutions, apparent solid‐like rheology is seen. However, no bulk structural features are found to explain it. Interfacial rheology and robust modelling reveal that this arises from molecular associations at the air–water interface ...

A Multiscale Guide to Brownian Motion [PDF]

open access: yesJ. Phys. A 49, 043001 (2016), 2015
We revise the Levy's construction of Brownian motion as a simple though still rigorous approach to operate with various Gaussian processes. A Brownian path is explicitly constructed as a linear combination of wavelet-based "geometrical features" at multiple length scales with random weights.

Soft ULC Microgels at the Interface Interact and Flow as Hertzian‐Like Colloids

open access: yesAdvanced Materials Interfaces, EarlyView.
Monolayers of soft ULC microgels, studied combining interfacial rheology, AFM and computer simulations, exhibit isoelastic points. At these points, the measured stiffness of the monolayer remains constant despite large differences in particle concentration.

A Brownian sheet martingale with the same marginals as the arithmetic average of geometric Brownian motion. [PDF]

open access: yes, 2008
We construct a martingale which has the same marginals as the arithmetic average of geometric Brownian motion. This provides a short proof of the recent result due to P.

Geometric Brownian motion with delay: mean square characterisation [PDF]

open access: yesProceedings of the American Mathematical Society, 2008
A geometric Brownian motion with delay is the solution of a stochastic differential equation where the drift and diffusion coefficient depend linearly on the past of the solution, i.e. a linear stochastic functional differential equation. In this work the asymptotic behavior in mean square of a geometric Brownian motion with delay is completely ...

Estimation Of Tail Parameter For Geometric Brownian Motion

open access: yesAl-Qadisiyah Journal of Pure Science, 2021
Right-tailed distributions are very important in many applications. There are many studies estimating the tail index. In this paper, we will estimate the tail parameter  using the three (the Direct, Bootstrap and Double Bootstrap) methods. Our aim is to illustrate the best way to estimate the -stable with  using simulation and real data for the daily ...
