DERIVATIONS ON SUBRINGS OF MATRIX RINGS
Chun, Jang-Ho; Park, June-Won;

Abstract
For a lower niltriangular matrix ring $\small{A=NT_n(K)(n{\geq}3)}$, we show that every derivation of A is a sum of certain diagonal, trivial extension and strongly nilpotent derivation. Moreover, a strongly nilpotent derivation is a sum of an inner derivation and an uaz-derivation.
