Very good gradings on structural matrix rings

Patrik Lundström, Johan Öinert, Laura Orozco +1

Let $R$ be a nonzero associative unital ring, let $G$ be a group, and let $ρ$ be a preorder on ${1, \dots, n}$ . A $G$ -grading on $ρ$ induces a very good $G$ -grading on the structu…

Very good gradings on matrix rings are epsilon-strong

Patrik Lundström, Johan Öinert, Laura Orozco +1

We investigate properties of group gradings on matrix rings $M_{n} (R)$ , where $R$ is an associative unital ring and $n$ is a positive integer. More precisely, we introduce very good…

The graded structure of Leavittt path algebras viewed as partial skew group rings

Daniel Gonçalves, Laura Orozco, Héctor Pinedo

Let $E$ be a directed graph, $K$ be a field, and $F$ be the free group on the edges of $E$ . In this work, we use the isomorphism between Leavitt path algebras and p…
