A note on the simplicity of skew polynomial rings of derivation type. (English) Zbl 1117.16016
Summary: In earlier papers we have obtained necessary and sufficient conditions for the simplicity of an iterated skew polynomial ring defined over a ring $$R$$ with respect to a finite set of derivations of $$R$$ commuting with each other.
In the present paper a sufficient condition is obtained for the simplicity of an iterated skew polynomial ring defined over a ring $$R$$ of characteristic zero with respect to a finite set of derivations of $$R$$ not necessarily commuting with each other. As an application we construct such a ring over the coordinate ring of the real sphere.
