Uniquely strongly clean group rings
摘要
Abstract
A ring is called uniquely strongly clean if every element is uniquely the sum of an idempotent and a unit that commute.The structure of uniquely strongly clean group rings is studied in this paper.It is proved that if G is a locally fi⁃nite group,then group ring RG is uniquely strongly clean if and only if R is uniquely strongly clean and G is a 2⁃group.关键词
