Abstract
Let A be a ring, ϕ be an injective endomorphism of A, and let \(A_r \left[ {x,\varphi } \right] \equiv R\) be the right skew polynomial ring. If all right annihilator ideals of A are ideals, then R is a right Bezout ring \( \Leftrightarrow A\) is a right Rickartian right Bezout ring, ϕ(e)=e for every central idempotent e∈A, and the element ϕ(a) is invertible in A for every regular a∈A. If A is strongly regular and n≥ 2, then R/x n R is a right Bezout ring \( \Leftrightarrow \) R/x n R is a right distributive ring \( \Leftrightarrow \) R/x n R is a right invariant ring \( \Leftrightarrow \) ϕ(e)=e for every central idempotent e∈A. The ring R/x 2 R is right distributive \( \Leftrightarrow \) R/x n R is right distributive for every positive integer n \( \Leftrightarrow \) A is right or left Rickartian and right distributive, ϕ(e)=e for every central idempotent e∈A and the ϕ(a) is invertible in A for every regular a∈A. If A is a ring which is a finitely generated module over its center, then A[x] is a right Bezout ring \( \Leftrightarrow \) A[x]/x 2 A[x] is a right Bezout ring \( \Leftrightarrow \) A is a regular ring.
