Simple Semigroup Graded Rings
Patrik Nystedt, Johan Öinert
We show that if is a, not necessarily unital, ring graded by a semigroup equipped with an idempotent such that is cancellative at , the non-zero elements of $eGe…

Maximal commutative subrings and simplicity of partial skew group rings
Johan Öinert
In this article, we show that for a partial skew group ring R*G, where R is a commutative ring, each non-zero ideal of R*G intersects R non-trivially if and only if R is a maximal…

Simple Rings and Degree Maps
Patrik Nystedt, Johan Öinert
For an extension A/B of neither necessarily associative nor necessarily unital rings, we investigate the connection between simplicity of A with a property that we call A-simplicit…
