Very good gradings on structural matrix rings
Patrik Lundström, Johan Öinert, Laura Orozco +1
Let be a nonzero associative unital ring, let be a group, and let be a preorder on . A -grading on induces a very good -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 , where is an associative unital ring and 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 be a directed graph, be a field, and be the free group on the edges of . In this work, we use the isomorphism between Leavitt path algebras and p…
