Alten proved in [4] that the FEP holds for commutative residuated lattices that satisfy any knotted rule. A class of algebras K is said to have the FEP, if for every algebra A in K and every finite partial subalgebra B of A, there exists a finite algebra D in K such that B embeds into D. B is a finite partial subalgebra of A, if B is a finite subset of A and each n−ary operation f on A induces ...
