Abstract
The notion of (regular) -derivations of a BCI-algebra is introduced, some useful examples are discussed, and related properties are investigated. The condition for a -derivation to be regular is provided. The concepts of a -invariant -derivation and -ideal are introduced, and their relations are discussed. Finally, some results on regular -derivations are obtained.
