On representable ordered residuated semigroups
We show that the equational theory of representable lattice-ordered residuated semigroups is not finitely axiomatizable. We apply this result to the problem of completeness of substructural logics.
متن کاملDivisibility Tests for Smarandache Semigroups
Two Divisibility Tests for Smarandache semigroups are given . Further, the notion of divisibility of elements in a semigroup is applied to characterize the Smarandache semigroups. Examples are provided for justification.
متن کاملOn Representable Mappings of Semigroups into Cardinals
Let S be a semigroup and f be a mapping of S into the class of nonzero cardinal numbers. The mapping f is said to be representable if there exist a groupoid G and a homomorphism h of G onto S such that Ker(h) is the least congruence of G for which the corresponding factor is a semigroup and f(a) = Cardh(a) for all a ∈ S. The investigation of representable mappings (see the papers [2] and [3]) i...
متن کاملThe equational theories of representable residuated semigroups
We show that the equational theory of representable lower semilattice-ordered residuated semigroups is finitely based. We survey related results.
متن کاملPerfect divisibility and 2-divisibility
A graph G is said to be 2-divisible if for all (nonempty) induced subgraphs H of G, V (H) can be partitioned into two sets A,B such that ω(A) < ω(H) and ω(B) < ω(H). A graph G is said to be perfectly divisible if for all induced subgraphs H of G, V (H) can be partitioned into two sets A,B such that H[A] is perfect and ω(B) < ω(H). We prove that if a graph is (P5, C5)-free, then it is 2-divisibl...
