Unique factorization in modules and symmetric algebras
Necessary and sufficient conditions are given for a torsionfree module M over a UFD D to admit a smallest factorial module containing it. This factorial hull is nMp, the intersection taken over all height one primes of D. In case M is finitely generated,

Multiplicative structure of generalized Koszul complexes
A multiplicative structure is defined for the generalized Koszul complexes K( APf) associated with the exterior powers of a map f: R"' -. RX where R is a commutative ring and m > n. With this structure K( Af ) becomes a differential graded R-algebra over

Characterization of Jordan centralizers and Jordan two-sided centralizers on triangular rings without assuming unity [PDF]
The main purpose of this paper is to show that every Jordan centralizer and every Jordan two-sided centralizer is a centralizer on triangular rings without assuming unity. As an application, we prove that every Jordan generalized derivation on a triangular ring is a two-sided generalized derivation. Some other related results are also discussed.

Steady growth of length function and Malcev algebras [PDF]
We introduce and investigate the algebras of steadily growing length, that is the class of algebras, where the length is bounded by a linear function of the dimension. In particular we show that Malcev algebras belong to this class and establish the exact upper bound for its length.

Commuting Jordan derivations on triangular rings are zero [PDF]
The main purpose of this article is to show that every commuting Jordan derivation on triangular rings (unital or not) is identically zero. Using this result, we prove that if $\mathcal{A}$ is a 2-torsion free ring such that it is either semiprime or satisfies Condition (P), then every commuting Jordan derivation from $\mathcal{A}$ into itself, under ...

Homomorphic images of affine quandles [PDF]
We are interested in abstract conditions that characterize homomorphic images of affine quandles. Our main result is a two-fold characterization of this class: one by a property of the displacement group, the other one by a property of the corresponding affine mesh.

Lie triple maps on generalized matrix algebras [PDF]
In this article, we introduce the notion of Lie triple centralizer as follows. Let $\mathcal{A}$ be an algebra, and $\phi:\mathcal{A}\to\mathcal{A}$ be a linear mapping. we say $\phi$ is a Lie triple centralizer whenever $\phi([[a,b],c])=[[\phi(a),b],c]$ for all $a,b,c\in\mathcal{A}$.

On Wreath Products of One-Class Association Schemes [PDF]
We give a full description of the algebraic structures of the Bose-Mesner algebra and Terwilliger algebra of the wreath product of one-class association schemes.

Lie higher derivations of arbitrary triangular algebras [PDF]
Motivated by the works of Wang [Y. Wang, \textit{Lie (Jordan) derivations of arbitrary triangular algebras,} Aequationes Mathematicae, \textbf{93} (2019), 1221-1229] and Moafian et al. [F. Moafian and H. R. Ebrahimi Vishki, \textit{Lie higher derivations on triangular algebras revisited,} Filomat, \textbf{30}(12) (2016), 3187-3194.], we shall study Lie

Nonlinear Jordan Derivations of Triangular Algebras [PDF]
In this paper we prove that any nonlinear Jordan derivation on triangular algebras is an additive derivation. As a byproduct, we obtain that any nonlinear Jordan derivation on nest algebras over infinite dimensional Hilbert spaces is inner.
