New symmetries of Black-Scholes equation
International Journal of Mathematics and Computers in Simulation, 2020 This work presents the comparison study between neural super-twisting sliding mode control (NSTSM) and adaptive-network-based fuzzy inference system-STSM (ANFIS-STSM) algorithm of the doubly fed induction generator (DFIG) controlled by direct power control (DPC). The mathematical model of the three-phase DFIG has been described. The descriptions of the

A non-linear Black-Scholes equation [PDF]
International Journal of Business Performance and Supply Chain Modelling, 2009 We study a modification of the Black-Scholes equation allowing for uncertain volatility. The model leads to a partial differential equation with non-linear dependence upon the highest derivative. Under certain assumptions, we show existence and uniqueness of a solution to the Cauchy problem.

Chaos for generalized Black-Scholes equations
, 2023 The Nobel Prize winning Black-Scholes equation for stock options and the heat equation can both be written in the form \[ \frac{\partial u}{\partial t}=P_2(A)u, \] where $P_2(z)=αz^2+ βz+γ$ is a quadratic polynomial with $α> 0$. In fact, taking $A = x\frac{\partial}{\partial x}$ on functions on $[0,\infty) \times [0,\infty)$ the previous equality ...

Strategic Change, EarlyView.ABSTRACT Start‐up CEOs are usually more aligned with the interests of the venture board compared to CEOs in legacy firms, and therefore it is usual to conclude that the traditional agency problem is lower in ventures. In this article, it is argued that this is only half of the story, and that the agency problem is reversed in early ventures such that ...

Qualitatively Stable Schemes for the Black–Scholes Equation
Fractal and Fractional, 2023 In this paper, the Black–Scholes equation is solved using a new technique. This scheme is derived by combining the Laplace transform method and the nonstandard finite difference (NSFD) strategy. The qualitative properties of the method are discussed, and

Systems Research and Behavioral Science, EarlyView.ABSTRACT This study investigates the relationship between cybersecurity capabilities (CCs) and cybersecurity performance (CP) across diverse regional contexts, employing ordinary least squares (OLS) and random forest (RF) regression models. The research highlights how economic, political and cultural factors shape CCs and their impact on CP ...
