Yousif, Mohamed F.; Zhou, Yiqiang; Zeyada, Nasr
 On Pseudo-Frobenius Rings It is proved here that a ring $R$ is right pseudo-Frobenius if and only if $R$ is a right Kasch ring such that the second right singular ideal is injective. Categories:16D50, 16L60

2. CMB 1997 (vol 40 pp. 221)

 On semiregular rings whose finitely generated modules embed in free modules We consider rings as in the title and find the precise obstacle for them not to be Quasi-Frobenius, thus shedding new light on an old open question in Ring Theory. We also find several partial affirmative answers for that question. Categories:16D10, 16L60, 16N20
