Linear Equations in the Ring of $\mathcal{S}\left(\mathcal{A}\right)$-Linearly Correlated Fuzzy Numbers

Abstract: This paper investigates the solutions of a family of certain linear fuzzy arithmetic equations that involve fuzzy numbers belonging to certain finite-dimensional vector spaces of $\mathbb{R}_{\mathcal{F}}$, called $\mathcal{S}\left(\mathcal{A}\right)$-linearly correlated fuzzy numbers. Here, $\A$ stands for a strongly linearly independent (SLI) set of fuzzy numbers. The arithmetic operations in the aforementioned linear equations are the sum in the vector space $\Sc(\A)$ and the so-called $\psi$-cross product that turns $\Sc(\A)$ into a commutative ring.
