The generalized path algebras over standardly stratified algebras

Wang, S. (Algebra and Discrete Mathematics, 2006)

In this note, it is proved that the generalized path algebras over standardly stratified algebras are also standardly stratified, and the generalized path algebras over quasi-hereditary algebras are also quasi-hereditary. ...
Twisted conjugacy classes of Automorphisms of Baumslag-Solitar groups

Fel’shtyn, A.; Goncalves, D.L. (Algebra and Discrete Mathematics, 2006)

Let φ : G → G be a group endomorphism where G is a finitely generated group of exponential growth, and denote by R(φ) the number of twisted φ-conjugacy classes. Fel’shtyn and Hill [7] conjectured that if φ is injective, ...
Weakly P-small not P-small subsets in Abelian groups

Banakh, T.; Lyaskovska, N. (Algebra and Discrete Mathematics, 2006)

Answering a question of D. Dikranjan and I. Protasov we prove that each infinite Abelian group contains a weakly P-small subset that is not P-small.
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 ...
