(F,G)-Derivasi Di Bg-Aljabar
A BG-algebra is a non-empty set X with a binary operation ∗ and
a constant 0 satisfying the following axioms: (B1) x∗x = 0, (B2) x∗0 = x,
and (BG) (x ∗ y) ∗ (0 ∗ y) = x for any x; y ∈ X, which is a generalization of
B-algebra, such that some of properties of BG-algebra have similarity by
B-algebra such as (B1) and (B2). However, some of the concepts in B-algebra
can also applied to BG-algebra, such as the concept of (f; g)-derivation. This
thesis discusses the concepts of f-derivation and (f; g)-derivation in BG-
algebra and some of related properties. The method in this research is in a
way similar to the f-derivation and (f; g)-derivation in B-algebra by
Ardekani and Davvas. The main results dene a (l; r)-f-derivation, a
(r; l)-f-derivation, a f-derivation, and left f-derivation in BG-algebras, and
obtained some of related properties. Also, a (l; r)-(f; g)-derivation, a (r; l)-(f; g)-
derivation, a (f; g)-derivation, and left (f; g)-derivation in BG-algebras
are dened, and obtained some of related properties.
Keywords: BG-algebra, (l; r)-f-derivation, (r; l)-f-derivation, f-derivation,
