Let T be a triangular algebra over a commutative ring R. In this paper, under some mild conditions on T , we prove that if for any x, y โ T with xy = 0 (resp. xy = p, where p is the standard idempotent of T ), then ฮด = d + ฯ , where d is a derivation of T and ฯ : T -โ Z(T ) (where Z(T ) is the cent
