元素[公式:如果环[Formula:see text]中的[Formula:see text]是一个幂等元[Formula:see text]和一个单位[Formula:see text]的和,则称之为干净的。这种干净的分解[Formula:see text]被称为强干净的if [Formula:see text]和特殊干净的if [Formula:see text]。本文证明了[Formula:see text]是Drazin可逆的当且仅当存在幂等元[Formula:see text]和单位[Formula:see text]使得[Formula:see text]对某个正整数[Formula:see text]既是强clean分解又是特殊clean分解。此外,Moore-Penrose逆和群逆的存在与某些非纯-干净分解的存在有关。
An element [Formula: see text] in a ring [Formula: see text] is called clean if it is the sum of an idempotent [Formula: see text] and a unit [Formula: see text]. Such a clean decomposition [Formula: see text] is said to be strongly clean if [Formula: see text] and special clean if [Formula: see text]. In this paper, we prove that [Formula: see text] is Drazin invertible if and only if there exists an idempotent [Formula: see text] and a unit [Formula: see text] such that [Formula: see text] is both a strongly clean decomposition and a special clean decomposition, for some positive integer [Formula: see text]. Also, the existence of the Moore–Penrose and group inverses is related to the existence of certain ∗-clean decompositions.
