摘要:A unit-picker is a map ɡ that associates to every ring R a well-defined set ɡ(R) of central units in R and is closed under taking inverses and which satisfies certain set containment conditions for quotient rings, corner rings and matrix rings. Let ɡ be a unit-picker. A ring R is called (strongly) nil ɡ-clean if for each a in R, a = ve + b, where v belongs to ɡ(R), e2 = e and b belong to R is nilpotent (and ab = ba). An extensive study of (strongly) nil ɡ-clean rings is conducted. When ɡ is specified, known results of the much studied (strongly) nil-clean rings and weakly nil-clean rings are re-proved and new results of other nil-clean-like rings are obtained.
