Abstract The aim of this study i to characterize quasi ideals and bi ideals in semigroups and rings with involution nevertheless the involutive version of some well known results for semigroups nd rings whithout involution are given by the way we investigate semigroups and rings in which a bi ideal is a quasi ideal an involution ring semigroup a is an associative semigroup with an additional unary operation called invlution subjected to the familiar identities. |
