| M. K- Sen defined a concept pseudo ideal of a riog in 1976, and use it to study division rings, fields and reqular rings. In this paper we have proved that does not exist any proper pseudo ideal in a non-Commutative division r ring and a finite field. Hence it is trivial that M- K- Sen's results on pseudo ideals of division rings, we have studed pseudo ideals of infinite fields, obt obtained some useful results on stucture of division rings . |
