LOCAL DERIVATIONS OF THE ALGEBRA OF UPPER TRIANGULAR MATRICES OVER COMMUTATIVE RINGS
Driss Aiat Hadj Ahmed (Morocco)
|
Abstract: We show that any linear map on a the algebra consisting of all upper triangular matrices over commutative rings, which at each point is equal to the value of some derivation of is either a derivation. |
Keywords and phrases: local derivation, derivation, upper triangular matrices. |
