On rings with associated elements
MT Koşan, TC Quynh, S Şahinkaya - Communications in Algebra, 2017 - Taylor & Francis
ABSTRACT A principal right ideal of a ring is called uniquely generated if any two elements
of the ring that generate the same principal right ideal must be right associated (ie, if for all a …
