Research Abstract

In 1965, Osofsky showed "right injective perfect rings are QF-rings" and raised : Are right injective right perfect rings QF ?. In 1976, Faith conjectured this is not true even for semiprimary rings. Since then, almost half centuly passed. In 2011, Oshiro showed this problem is true for many cases.
