Generalizing the Black and Scholes Equation Assuming Differentiable Noise

Journal of Applied Mathematics, Volume 2024, Issue 1, 2024.
This article develops probability equations for an asset value through time, assuming continuous correlated differentiable Gaussian distributed noise. Ito’s (1944) stochastic integral and a generalized Novikov’s (1919) theorem are used. As an example, the mathematical model is used to generalize the Black and Scholes’ (1973) equation for pricing ...

Stability and Uniqueness Results for the Nonseparated Boundary Conditions of Nonlinear Coupled System of Fractional Differential Equations

International Journal of Mathematics and Mathematical Sciences, Volume 2024, Issue 1, 2024.
In this article, the focus is on investigating the uniqueness, existence, and stability of a coupled system of fractional differential equations with non‐separated coupled boundary conditions. The uniqueness of solutions for the presented problem is discussed by employing the fixed‐point theorem.

The Exact Iterative Solution of Fractional Differential Equation with Nonlocal Boundary Value Conditions

Journal of Function Spaces, 2018
We deal with a singular nonlocal fractional differential equation with Riemann-Stieltjes integral conditions. The exact iterative solution is established under the iterative technique. The iterative sequences have been proved to converge uniformly to the

On Banach spaces of regulated functions of several variables. Analogue of the Riemann–Stieltjes integral

Vestnik Udmurtskogo Universiteta Matematika Mekhanika Komp yuternye Nauki
In the previous work of the authors, the concept of a regulated function of several variables $f\colon X\to\mathbb R$ was introduced, where $X\subseteq \mathbb R^n.$ The definition is based on the concept of a special partition of the set $X$ and the ...

Comparative Statics With Linear Objectives: Normality, Complementarity, and Ranking Multi‐Prior Beliefs

Econometrica, Volume 92, Issue 1, Page 167-200, January 2024.
We formulate an order over constraint sets , called the parallelogram order, which guarantees that argmin{p ⋅ x:x ∈ A} increases in the product order as A increases in the parallelogram order, for any vector . Using this result, we characterize the utility/production functions that lead to normal demand as well as the closely related class of ...
