Abstract
A qualitative analysis of a second-order fuzzy difference equation featuring a quadratic term was recently explored in this journal. The study presented was limited to a second-order equation. Here, we generalize the study to a higher-order fuzzy difference equation with a quadratic component. Furthermore, we establish adequate conditions on the qualitative dynamics involving boundedness, persistence, and the convergence of positive fuzzy solutions to the equation. In addition, we provide two simulation instances to validate our theoretical examination.
