f-DERIVATIONS AND (f; g)-DERIVATIONS OF MV -ALGEBRAS

Abstract

Recently, the algebraic theory of MV -algebras is intensively studied. <br />In this paper, we extend the concept of derivation of $MV$-algebras and we give some<br />illustrative examples. Moreover, as a generalization of derivations of $MV$ -algebras<br />we introduce the notion of $f$-derivations and $(f; g)$-derivations of $MV$-algebras.<br />Also, we investigate some properties of them.
