On the Coprimeness Property of Discrete Systems without the Irreducibility Condition
In this article, we investigate the coprimeness properties of one and two-dimensional discrete equations in a situation where the equations are decomposable into several factors of polynomials. After experimenting on a simple equation, we shall focus on some higher power extensions of the Somos-4 eq...
