Embedding Problems for Graphs and Hypergraphs [PDF]

open access: yes, 2010
This thesis deals with the problem of finding some substructure within a large graph or hypergraph. In the case of graphs, we consider the substructures consisting of fixed subgraphs or families of subgraphs, perfect graph packings and spanning subgraphs.

The Mediating Role of Digital Market and Payment Systems in ICT‐Based Food Security Management

open access: yeseFood, Volume 7, Issue 4, August 2026.
ICT enhances food security management in Bangladesh by linking production, distribution, and digital market systems. Digital Market and Payment (DMP) mediates the relationship between Food Production and Distribution (FPD) and Food Security Management (FSM), highlighting the transformative role of digital innovation in sustainable food governance ...

Weak, Strong and Mixed Extensions of Relations to Spaces of Ultrafilters

open access: yesMathematical Logic Quarterly, Volume 72, Issue 3, August 2026.
ABSTRACT The use of nonstandard methods to characterize properties of weak, strong and mixed extensions of congruences to ultrafilters has been the main topic of several recent papers, focused mostly on congruences and divisions. We show that similar methods can be used to extend these characterizations to arbitrary relations and their interplay.

Not “seeing race”: The effects of institutionalized racial colorblindness on college admissions decisions

open access: yesAnalyses of Social Issues and Public Policy, Volume 26, Issue 2, August 2026.
Abstract Racial colorblindness refers to the prescriptive belief that race should not influence institutional practices or interpersonal interactions. Though racial colorblind ideology was championed in the 2023 Supreme Court ruling reversing affirmative action in college admissions, existing research suggests that such beliefs may perpetuate racial ...

Treewidth Versus Clique Number. V. Further Connections With Tree‐Independence Number

open access: yesJournal of Graph Theory, Volume 112, Issue 3, Page 337-351, July 2026.
ABSTRACT We continue the study of ( tw , ω )‐bounded graph classes, that is, hereditary graph classes in which large treewidth is witnessed by the presence of a large clique, and the relation of this property to boundedness of the tree‐independence number, a graph parameter introduced independently by Yolov in 2018 and by Dallard, Milanič, and Štorgel ...
