On the Solution of the Multi-Asset Black-Scholes Model: Correlations, Eigenvalues and Geometry [PDF]

open access: yes, 2015
In this paper, the multi-asset Black-Scholes model is studied in terms of the importance that the correlation parameter space (equivalent to an N dimensional hypercube) has in the solution of the pricing problem. It is shown that inside of this hypercube

Advancing the mapping of vegetation structure in savannas using Sentinel‐1 imagery

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
As vegetation structure monitoring is important for the understanding and conservation of savanna ecosystems, we explored the utility of C‐band synthetic aperture radar imagery for mapping both grassland and woody vegetation structure in the Greater Serengeti‐Mara Ecosystem.

A New Homotopy Transformation Method for Solving the Fuzzy Fractional Black–Scholes European Option Pricing Equations under the Concept of Granular Differentiability

open access: yesFractal and Fractional, 2022
The Black–Scholes option pricing model is one of the most significant achievements in modern investment science. However, many factors are constantly fluctuating in the actual financial market option pricing, such as risk-free interest rate, stock price,

Impacts of African elephants and other environmental drivers on trees nested in by critically endangered white‐backed vultures

open access: yesWildlife Biology, EarlyView.
The decline of white‐backed vultures Gyps africanus (hereafter termed vultures) across Africa highlights the need to understand their habitat and nesting requirements, especially in protected areas where African elephants Loxodonta africana can impact the trees in which vultures build their nests.

Below the leaves: Integrating above‐ and below‐ground phenology for earth‐system predictability

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Almost every aspect of biological systems has phenology—a pattern in activity or function linked to annual cycles. Most terrestrial phenology research focusses on leaves, the onset of leaf out or senescence.

Laplace Transform Homotopy Perturbation Method for the Two Dimensional Black Scholes Model with European Call Option

open access: yes, 2017
The Black Scholes model is a well-known and useful mathematical model in financial markets. In this paper, the two-dimensional Black Scholes equation with European call option is studied. The explicit solution of this problem is carried out in the form of

The effect of addback statutes on CEO compensation

open access: yesAccounting &Finance, Volume 65, Issue 1, Page 793-818, March 2025.
Abstract Exploiting the adoption of addback statutes, which occurred at different times, as exogenous shocks to corporate taxable income, we examine the effect of tax policy changes on the compensation of chief executive officers (CEOs). We provide evidence that CEOs of firms headquartered in states affected by addback statutes experienced a decrease ...
