Strongly drazin inverse in rings
WebIn 2024, Wang [19] gave the notion of the strong Drazin inverse in a ring. An element. a ∈ R. is said to be strongly Drazin invertible [19] if there exists. x ∈ R. such that. xax = x, ax = xa, and. a−ax ∈ R. nil. In this case, x. is unique if it exists and is called the strong Drazin … WebJan 2, 2024 · An element $a\in R$ has generalized n-strongly Drazin inverse if there exists $x\in R$ such that $xax=x, x\in comm^2(a), a^n-ax\in R^{qnil}.$ For any $a,b\in R$, we prove that $1-ab$ has generalized n-strongly Drazin inverse if and only if $1-ba$ has …

WebJul 5, 2016 · Denote by R s D the set of all strongly Drazin invertible elements of R. If δ ⊆ {2, 5, 7} and b satisfies the equations ( i) for all i ∈ δ, then b is an δ -inverse of a. The set of all δ -inverse of a is denoted by a { δ }. Observe that a { 2, 5, 7 } = { a ′ } . Lemma 1.1 [21, … WebRecently, a new type of generalized inverse called the n-strong Drazin inverse was introduced by Mosić in the setting of rings. Namely, let R be a ring and n be a positive integer, an element x ∈ R is called the n -strong Drazin inverse of a ∈ R if it satisfies x a x = …
