Covering Numbers in Linear Algebra
The American Mathematical Monthly, 2012 We compute the minimal cardinality of a covering (resp. an irredundant covering) of a vector space over an arbitrary field by proper linear subspaces. Analogues for affine linear subspaces are also given.

On the dimension of the minimal vertex cover semigroup ring of an unmixed bipartite graph
Le Matematiche, 2008 In a paper in 2008, Herzog, Hibi and Ohsugi introduced and studied the semigroup ring associated to the set of minimal vertex covers of an unmixed bipartite graph.

In Situ Graph Reasoning and Knowledge Expansion Using Graph‐PRefLexOR
Advanced Intelligent Discovery, EarlyView.Graph‐PRefLexOR is a novel framework that enhances language models with in situ graph reasoning, symbolic abstraction, and recursive refinement. By integrating graph‐based representations into generative tasks, the approach enables interpretable, multistep reasoning.

A Thread Algebra with Multi-Level Strategic Interleaving
Theory of Computing Systems, 2005 In a previous paper we developed an algebraic theory about threads and a form of concurrency where some deterministic interleaving strategy determines how threads that exist concurrently are interleaved.

The standard graded property for vertex cover algebras of quasi-trees
Le Matematiche, 2008 In [5] the authors characterize the vertex cover algebras which are tandard graded. In this paper we give a simple combinatorial criterion for the standard graded property of vertex cover algebras in the case of quasi-trees.

Remedies for Misapplications of Sylvester’s Criterion: A Pedagogic Illustration
Spreadsheets in Education, 2021 Sylvester’s criterion, which verifies the positive definiteness of any real symmetric matrix by examining the signs of all leading principal minors, is an excellent analytical tool.
