Quasi-Frobenius Rings and Nakayama Permutations of Semiperfect Rings
We say that \({\mathcal{A}}\) is a ring with duality for simple modules, or simply a DSM-ring, if, for every simple right (left) \({\mathcal{A}}\) -module U, the dual module U* is a simple left (right) \({\mathcal{A}}\) -module. We prove that a semiperfect ring is a DSM-ring if and only if...

Ukrains’kyi Matematychnyi Zhurnal| Zusammenfassung: | We say that \({\mathcal{A}}\) is a ring with duality for simple modules, or simply a DSM-ring, if, for every simple right (left) \({\mathcal{A}}\) -module U, the dual module U* is a simple left (right) \({\mathcal{A}}\) -module. We prove that a semiperfect ring is a DSM-ring if and only if it admits a Nakayama permutation. We introduce the notion of a monomial ideal of a semiperfect ring and study the structure of hereditary semiperfect rings with monomial ideals. We consider perfect rings with monomial socles. |
