Novel ANN Method for Solving Ordinary and Time-Fractional Black–Scholes Equation
Complexity, 2021 The main aim of this study is to introduce a 2-layered artificial neural network (ANN) for solving the Black–Scholes partial differential equation (PDE) of either fractional or ordinary orders.

Inscribing Impact: Measurement Practices in the Making of Moral Markets
Journal of Management Studies, Volume 63, Issue 3, Page 1229-1263, May 2026.Abstract Moral markets, designed to generate positive impact on pressing social and environmental challenges, are transforming traditional market practices by including more than economic considerations in their operations. The importance of these markets continues to grow as investors, regulators, and consumers increasingly put pressure on companies ...

Long memory stochastic volatility in option pricing
, 2004 The aim of this paper is to present a simple stochastic model that accounts for the effects of a long-memory in volatility on option pricing. The starting point is the stochastic Black-Scholes equation involving volatility with long-range dependence.

Global Natural Soil N2O Emissions: An Analysis With a Global Biogeochemistry Model From 1990 to 2023
Global Biogeochemical Cycles, Volume 40, Issue 4, April 2026.Abstract Atmospheric N2O, the dominant ozone‐depleting substance and a potent greenhouse gas, has risen notably over recent decades. Using a process‐based model, we simulated the sensitivity of N2O emissions from undisturbed natural soils to the representation of historical land‐cover change from 1990 to 2023 by factoring the effects of atmospheric ...

An adaptive moving mesh method for a time-fractional Black–Scholes equation
Advances in Difference Equations, 2019 In this paper we study the numerical method for a time-fractional Black–Scholes equation, which is used for option pricing. The solution of the fractional-order differential equation may be singular near certain domain boundaries, which leads to ...

Journal of Ecology, Volume 114, Issue 4, April 2026.We compared soil organic carbon (SOC) across six savanna–forest boundaries in South Africa. Surprisingly, savanna and forest soils contained comparable SOC stocks. While vegetation change shifted the carbon source from C4‐grasses to C3‐trees, total carbon storage was driven by local soil texture (clay/silt), proving that increasing tree cover does not ...

ANALYTICAL STUDY AND GENERALISATION OF SELECTED STOCK OPTION VALUATION MODELS [PDF]
, 2017 In this work, the classical Black-Scholes model for stock option valuation on the basis of some stochastic dynamics was considered. As a result, a stock option val- uation model with a non- xed constant drift coe cient was derived. The classical Black-

Correction to Black-Scholes formula due to fractional stochastic volatility
, 2017 Empirical studies show that the volatility may exhibit correlations that decay as a fractional power of the time offset. The paper presents a rigorous analysis for the case when the stationary stochastic volatility model is constructed in terms of a ...
