Revising the Magnitude and Trends of the Global Methane Soil Sink With Process‐Based, Machine‐Learning, and Atmospheric Inversion Modeling Approaches

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 7, July 2026.
Abstract Methane (CH4) oxidation by microbes is the largest biological sink of global methane, yet its magnitude and long‐term variability remain uncertain. Here, we combined process‐based (PB), machine‐learning (ML), and atmospheric inversion approaches to evaluate the global methane soil sinks and its implication for the atmospheric CH4 budget in ...

Accurate and Efficient Computations of the Greeks for Options Near Expiry Using the Black-Scholes Equations

Discrete Dynamics in Nature and Society, 2016
We investigate the accurate computations for the Greeks using the numerical solutions of the Black-Scholes partial differential equation. In particular, we study the behaviors of the Greeks close to the maturity time and in the neighborhood around the ...

Perpetual Futures Pricing

Mathematical Finance, Volume 36, Issue 3, Page 481-499, July 2026.
ABSTRACT Perpetual futures are contracts without expiration date in which the anchoring of the futures price to the spot price is ensured by periodic funding payments from long to short. We derive explicit expressions for the no‐arbitrage price of various perpetual contracts, including linear, inverse, and quantos futures in both discrete and ...

Solving the Black-Scholes Partial Differential Equation via the Solution Method for a One-Dimensional Heat Equation: A Pedagogic Approach with a Spreadsheet-Based Illustration

Spreadsheets in Education, 2019
The derivation of the Black-Scholes option pricing model, if covered in detail, is by far the most complicated among all major models in the finance curriculum.

Lie Symmetry Analysis of a Nonlinear Black–Scholes Equation in Illiquid Markets

International Journal of Mathematics and Mathematical Sciences
We have conducted comprehensive Lie symmetry analysis of a nonlinear Black–Scholes equation that arises in illiquid markets. The equation incorporates nonlinearities arising from market constraints, such as transaction costs and liquidity effects.

The Riccati System and a Diffusion-Type Equation

Mathematics, 2014
We discuss a method of constructing solutions of the initial value problem for diffusion-type equations in terms of solutions of certain Riccati and Ermakov-type systems. A nonautonomous Burgers-type equation is also considered. Examples include, but are

Relativistic Black–Scholes Equation

Revista Mexicana de Economía y Finanzas
The Relativistic Black Scholes Model presented in this paper is a generalization that is not very well known since the original version of 1973, because its effects are still not very significant. Actually, any small advantage in information knowledge in the High-Frequency Trading can become great arbitrage opportunities.
