A ring R is called (left principally) quasi-Baer if the left annihilator of every (principal) left
ideal of R is generated by an idempotent. We show that if R is (left principally) quasi-Baer …

Throughout this paper R denotes an associative ring with unity. Recall from [Ka2) that R is a
Baer ring if the right annihilator of every nonempty subset of R is generated, as a right ideal …

A ring R with an automorphism α and an α-derivation δ is called (α, δ)-quasi-Baer (resp.,
quasi-Baer) if the right annihilator of every (α, δ)-ideal (resp. ideal) of R is generated by an …

A ring R is called quasi-Baer if the right annihilator of every right ideal of R is generated by
an idempotent as a right ideal. We investigate the quasi-Baer property of skew group rings …

We first study the quasi-Baerness of R [x; σ, δ] over a quasi-Baer ring R when σ is an
automorphism of R, obtaining an affirmative result. We next show that if R is a right …

We say a ring with identity is a generalized right (principally) quasi-Baer if for any (principal)
right ideal I of R, the right annihilator of In is generated by an idempotent for some positive …

A ring R with unity is called a (quasi-) Baer ring if the left annihilator of every (left ideal)
nonempty subset of R is generated (as a left ideal) by an idempotent. Armendariz has shown …

We say a ring R with unity is weakly principally quasi-Baer or simply (weakly pq-Baer) if the
right annihilator of a principal right ideal is right s-unital by right semicentral idempotents …

A ring R is said to be a Baer (respectively, quasi-Baer) ring if the left annihilator of any
nonempty subset (respectively, any ideal) of R is generated by an idempotent. It is first …

A ring R is called “quasi-Baer” if the right annihilator of every right ideal is generated, as a
right ideal, by an idempotent. It can be seen that a quasi-Baer ring cannot be a right …
