Jordan Derivations of Special Subrings of Matrix Rings

Umut Sayın, Feride Kuzucuoğlu

Let $K$ be a 2-torsion free ring with identity and $R_{n} (K, J)$ be the ring of all $n \times n$ matrices over $K$ such that the entries on and above the main diagonal are elements o…

Lie Derivations of a Matrix Ring over an Associative Ring

Umut Sayın, Feride Kuzucuoğlu

Let $K$ be a 2-torsion free ring with identity. We give a description of the Lie derivations of $R = R_{n} (K, J) = N T_{n} (K) + M_{n} (J)$ , the ring of all $n \times n$ matrices over $K$ suc…
