Simple graded rings, non-associative crossed products and Cayley-Dickson doublings
Patrik Nystedt, Johan Öinert
We show that if a non-associative unital ring is graded by a hypercentral group, then the ring is simple if and only if it is graded simple and the center of the ring is a field. T…
Quasi-duo differential polynomial rings
Mai Hoang Bien, Johan Öinert
In this article we give a characterization of left (right) quasi-duo differential polynomial rings. In particular, we show that a differential polynomial ring is left quasi-duo if…
Epsilon-strongly graded rings, separability and semisimplicity
Patrik Nystedt, Johan Öinert, Héctor Pinedo
We introduce the class of epsilon-strongly graded rings and show that it properly contains both the class of strongly graded rings and the class of unital partial crossed products.…
Artinian and noetherian partial skew groupoid rings
Patrik Nystedt, Johan Öinert, Héctor Pinedo
Let be a partial action of a groupoid on a non-associative ring and let be the associa…
