Character Modules
Character modules, submodules of a free module, and quasi-Frobenius rings.
Characterisations of Semi-Prime Archimedean f-algebras.
Characteristic of M-polysymmetrical Hyperrings and some properties of M-Polysymmetrical Hyperrings with Unity
Characterization of a radical of group rings over finite prime fields.
Characterization of fuzzy neighborhood commutative division rings. II.
Characterization of matrix types of ultramatricial algebras.
Characterization of Regular Semirings
Characterizations of Jordan derivations on triangular rings: additive maps Jordan derivable at idempotents.
Characterizations of partial isometries and two special kinds of EP elements
We give some sufficient and necessary conditions for an element in a ring to be an EP element, partial isometry, normal EP element and strongly EP element by using solutions of certain equations.
Characterizations of projective and -projective semimodules.
Characterizations of Semi-Perfect and Perfect Modules.
Characterizations of semiperfect and perfect rings.
We characterize semiperfect modules, semiperfect rings, and perfect rings using locally projective covers and generalized locally projective covers, where locally projective modules were introduced by Zimmermann-Huisgen and generalized locally projective covers are adapted from Azumaya’s generalized projective covers.
