We call this kind of ringsqnil-duo. Firstly, someproperties of quasinilpotents in a ring are provided. Then the set of quasinilpotents is applied tothe duo property of rings, in this perspective, we introduceand study right (resp., left) qnil-duorings. We show that this concept is not left-right symmetric. Among others, it is proved that if theHurwitz series ringH(R;α)is right qnil-duo, thenRis right qnil-duo. Every right qnil-duo ring isabelian. A right qnil-duo exchange ring has stable range 1.EnglishQuasinilpotentElementDuo ringQnil-duo ringArticle10.15330/cmp.13.2.485-5002313-0210
