Zero-sum subsets of decomposable sets in Abelian groups

Banakh, T.; Ravsky, A. (Algebra and Discrete Mathematics, 2020)

A subset D of an abelian group is decomposable if ∅ ≠ D ⊂ D + D. In the paper we give partial answers to an open problem asking whether every finite decomposable subset D of an abelian group contains a non-empty subset ...
(λ, μ)-fuzzy interior ideals of ordered Г-semigroups

Feng, Yu.; Corsini, P. (Algebra and Discrete Mathematics, 2013)

For all λ, μ ∈ [0, 1] such that λ < μ, we first introduced the definitions of (λ, μ)-fuzzy ideals and (λ, μ)-fuzzy interior ideals of an ordered Γ-semigroup. Then we proved that in regular and in intra-regular ordered ...
τ-complemented and τ-supplemented modules

Al-Takhman, K.; Lomp, C.; Wisbauer, R. (Algebra and Discrete Mathematics, 2006)

Proper classes of monomorphisms and short exact sequences were introduced by Buchsbaum to study relative homological algebra. It was observed in abelian group theory that complement submodules induce a proper class of ...
