Symmetrization in Clean and Nil-Clean Rings
Izvestiya of Saratov University. New Series. Series: Mathematics. Mechanics. Informatics, 2020 A ring \(R\) is said to be \textsl{double nil-clean} or just \textsl{ D-nil-clean} for short if, for every \(a\in R\), there exists \(e\in (aRa)\cap Id(R)\) such that \(a=e+q\) for some \(q\in \mathrm{Nil}(R)\). Similarly, a ring \(R\) is said to be \textsl{double clean} or just \textsl{D-clean} for short if, for each \(a\in R\), there exists \(e\in ...
