Shallow Minors, Graph Products, and Beyond-Planar Graphs

R Hickingbotham, DR Wood - SIAM Journal on Discrete Mathematics, 2024 - SIAM
The planar graph product structure theorem of Dujmović et al.[J. ACM, 67 (2020), 22] states
that every planar graph is a subgraph of the strong product of a graph with bounded …

Product structure of graphs with an excluded minor

F Illingworth, A Scott, D Wood - Transactions of the American Mathematical …, 2024 - ams.org
This paper shows that $ K_t $-minor-free (and $ K_ {s, t} $-minor-free) graphs $ G $ are
subgraphs of products of a tree-like graph $ H $(of bounded treewidth) and a complete …

Sketching distances in monotone graph classes

L Esperet, N Harms, A Kupavskii - arxiv preprint arxiv:2202.09253, 2022 - arxiv.org
We study the two-player communication problem of determining whether two vertices $ x, y $
are nearby in a graph $ G $, with the goal of determining the graph structures that allow the …

Product Structure and Tree-Decompositions

CH Liu, S Norin, DR Wood - arxiv preprint arxiv:2410.20333, 2024 - arxiv.org
This paper explores the structure of graphs defined by an excluded minor or an excluded
odd minor through the lens of graph products and tree-decompositions. We prove that every …

[HTML][HTML] On graph classes with minor-universal elements

A Georgakopoulos - Journal of Combinatorial Theory, Series B, 2025 - Elsevier
A graph U is universal for a graph class C∋ U, if every G∈ C is a minor of U. We prove the
existence or absence of universal graphs in several natural graph classes, including graphs …

Structural properties of graph products

R Hickingbotham, DR Wood - Journal of Graph Theory, 2023 - Wiley Online Library

The product structure of squaregraphs

R Hickingbotham, P Jungeblut, L Merker… - Journal of Graph …, 2024 - Wiley Online Library
A squaregraph is a plane graph in which each internal face is a 4‐cycle and each internal
vertex has degree at least 4. This paper proves that every squaregraph is isomorphic to a …
