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

Sentience in cephalopod molluscs: an updated assessment
Biological Reviews, Volume 101, Issue 3, Page 1311-1333, June 2026.ABSTRACT This article evaluates the evidence for sentience – the capacity to have feelings – in cephalopod molluscs: octopus, cuttlefish, squid, and nautilus. Our framework includes eight criteria, covering both whether the animal's nervous system could support sentience and whether their behaviour indicates sentience.

Ecology and Evolution, Volume 16, Issue 6, June 2026.When ecological data are collected by many entities for different purposes, they can be difficult to locate and integrate; web applications can address this by standardizing submission, automating cleaning, and incentivizing contributions. We present P.I.

How Regulation and Global Standing Shape Stock Market Co‐Movements: A G20 Panel Study
International Review of Finance, Volume 26, Issue 2, June 2026.ABSTRACT Motivated by post‐2020 fragmentation and underexplored institutional‐geopolitical drivers, we examine how regulatory quality (RQ) and global power (GP) shape stock‐market co‐movements across 17 G20 economies. We estimate time‐varying correlations via ADCC‐GARCH, construct a scaled correlation index, and apply panel ARDL. We find that higher RQ

Monochromatic Graph Decompositions Inspired by Anti-Ramsey Theory and Parity Constraints
MathematicsWe open here many new tracks of research in anti-Ramsey Theory, considering edge-coloring problems inspired by rainbow coloring and further by odd colorings and conflict-free colorings. Let G be a graph and F any given family of graphs. For every integer

The size-Ramsey number of powers of paths
, 2019 Given graphs G and H and a positive integer q, say that G is q-Ramsey for H, denoted G → (H) q , if every q-coloring of the edges of G contains a monochromatic copy of H.

, 2022 The Ramsey number $R(r, b)$ is the least positive integer such that every edge 2-coloring of the complete graph $K_{R(r, b)}$ with colors red and blue either embeds a red $K_r$ or a blue $K_b$. We explore various methods to find lower bounds on $R(r,b)$,

An exploration in Ramsey theory
, 2020 We present several introductory results in the realm of Ramsey Theory, a subfield of Combinatorics and Graph Theory. The proofs in this thesis revolve around identifying substructure amidst chaos.

A multidimensional Ramsey theorem
Discrete AnalysisA multidimensional Ramsey theorem, Discrete Analysis 2024:21, 10 pp. Ramsey's theorem, the founding result of Ramsey theory, states that for every pair of positive integers $r$ and $k$ there exists $n$ such that if the edges of the complete graph $K_n ...
