Boij-S\"{o}derberg Decompositions of Lex-segment Ideals [PDF]
, 2015 Boij-S\"oderberg theory describes the scalar multiples of Betti diagrams of graded modules over a polynomial ring as a linear combination of pure diagrams with positive coefficients.

A topological study in the set of zero-dimensional subrings of a commutative ring [PDF]
summary:We investigate the relationship between the space $\mathcal {Z}(R,T)$, defined as the largest closed subset of a ring $T$ with respect to a countable topology, and the classical prime spectrum ${\rm Spect}(R)$ of a subring $R$.

U-factorizations in Commutative Rings with Zero Divisors [PDF]
, 2017 Let R be a commutative ring with identity. We define an alternate method of factorization, called a U-factorization, and extend several finite factorization characterizations to U ...

Homogeneous Weights and M\"obius Functions on Finite Rings [PDF]
, 2013 The homogeneous weights and the M\"obius functions and Euler phi-functions on finite rings are discussed; some computational formulas for these functions on finite principal ideal rings are characterized; for the residue rings of integers, they are ...

Independent sets of some graphs associated to commutative rings
, 2013 Let $G=(V,E)$ be a simple graph. A set $S\subseteq V$ is independent set of $G$, if no two vertices of $S$ are adjacent. The independence number $\alpha(G)$ is the size of a maximum independent set in the graph.

Centralizers in Free Associative Algebras and Generic Matrices
, 2019 In this short note, we complete a proof of Bergman's centralizer theorem for the free associative algebra using generic matrices approach based on our previous work Alexei Kanel Belov, Farrokh Razavinia, Wenchao Zhang, "Bergman's Centralizer Theorem and ...

On the direct product of fields with a geometric application
, 2019 In this paper, some new results on the direct product of fields are obtained. In particular, it is shown that every set $X$ can be made into a separated scheme, and this scheme is an affine scheme if and only if $X$ is a finite set.Comment: 9 ...
