They give illustrative examples and they also characterized the distributive lattice by symmetric f bi-derivation. In this paper we define the isotone symmetric f biderivation and get some interesting results about isotoneness. We also give the relations between the distributive, modular and isotone lattices by symmetric f bi-derivation.eninfo:eu-repo/semantics/closedAccessDerivationIsotoneLatticeSymmetric f bi-derivationArticle832432532-s2.0-84870335617Q4
