Abstract

NYSTEDT, Patrik. A survey of s-unital and locally unital rings. Integración - UIS [online]. 2019, vol.37, n.2, pp.251-260. Epub Oct 10, 2019. ISSN 0120-419X. https://doi.org/10.18273/revint.v37n2-2019003.

We gather some classical results and examples that show strict inclusion between the families of unital rings, rings with enough idempotents, rings with sets of local units, locally unital rings, s-unital rings and idempotent rings.

MSC2010: 1602, 16D99, 16S99, 16U99.

Keywords : Unital ring; rings with enough idempotents; rings with sets of local units; locally unital ring; s-unital ring; idempotent ring.
