摘要：
We say a ring with unity is right principally quasi-Baer (or simply, right p.q. -Baer) if the right annihilator of a principal right ideal is generated las a right ideal) by an idempotent. This class of rings includes the biregular rings and is closed under direct products and Morita invariance. The 2-by-2 formal upper triangular matrix rings of this class are characterized. Connections to related classes of rings (e.g., right PP, Baer, quasi-Baer, right FPF, right GFC, etc.) are investigated. Examples to illustrate and delimit the theory are provided.
