Simplicity of skew inverse semigroup rings with applications to Steinberg algebras and topological dynamics

Viviane Beuter, Daniel Gonçalves, Johan Öinert +1

Given a partial action $π$ of an inverse semigroup $S$ on a ring $A$ one may construct its associated skew inverse semigroup ring $A ⋊_{π} S$ . Our main resul…

Simplicity of Ore monoid rings

Patrik Nystedt, Johan Öinert, Johan Richter

Given a non-associative unital ring $R$ , a monoid $G$ and a set $π$ of additive maps $R \to R$ , we introduce the Ore monoid ring $R [π; G]$ , and, in a special case, the diff…

Group gradations on Leavitt path algebras

Patrik Nystedt, Johan Öinert

Given a directed graph $E$ and an associative unital ring $R$ one may define the Leavitt path algebra with coefficients in $R$ , denoted by $L_{R} (E)$ . For an arbitrary group $G$ , $L_…
