of its properties, defined a d -derivation ideal and gave conditions for an ideal
to be d-derivation.Two years later, Hamza and Al-Shehri [8] studied derivation
in BCK-algebras. In [9], Hamza and Al-Shehri defined a left derivation
in BCI-algebras and investigated a regular left derivation. In [17, 18], the
notions of derivations of weak BCC-algebras were studied and some related
properties were also investigated. In this paper, we introduce the notion of t
-derivation on BCC-algebras and obtain some of its related properties and we
characterized Ker dbyt-derivations .
