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

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, $\mathcal{A}$ 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 $\mathcal{S}(\mathcal{A})$ and the so-called $\psi$-cross product that turns $\mathcal{S}(\mathcal{A})$ into a commutative ring.
