WebMay 5, 2024 · ABSTRACT. We study the one-sided version of central Drazin inverses. An element a in a ring R is said to be left central Drazin invertible if there is x ∈ R such that x a ∈ C ( R), x a n + 1 = a n for some n ∈ N. The right central Drazin invertible elements can be defined similarly. It is shown that an element a ∈ R is central Drazin ... 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 = x , a x = x a and a n − a x ∈ R nil .
