On generalized $f$-derivations of lattice implication algebras

KyungHo Kim


In this paper, we introduce the notion of generalized $f$-derivation  of lattice implication algebra and investigate some related properties. Also, we prove that  if $D$ is a generalized $f$-derivation  associated with an $f$-derivation $d$ of $L,$ then $D(x\to y)=f(x)\to D(y)$ for all $x,  y\in L.$
