Integrality over ideal semifiltrations

Darij Grinberg

We study integrality over rings (all commutative in this paper) and over ideal semifiltrations (a generalization of integrality over ideals). We begin by reproving classical result…

Integrality of matrices, finiteness of matrix semigroups, and dynamics of linear and additive cellular automata

Alberto Dennunzio, Enrico Formenti, Darij Grinberg +1

Let $K$ be a finite commutative ring, and let $L$ be a commutative $K$ -algebra. Let $A$ and $B$ be two $n \times n$ -matrices over $L$ that have…
