Graphs of high girth have been much studied, especially in the context of the minimum vertex number of graphs of given girth and minimum degree. The authors study the treewidth \(\text{tw}(G)\) of a graph \(G\), giving a lower bound in terms of the girth \(g(G)\) and average degree \(d(G)\). They show that \[ \text{tw}(G)\geq c {1\over g(G)+1} (d(G)-1)^

Treewidth of display graphs: bounds, brambles and applications
Phylogenetic trees and networks are leaf-labelled graphs used to model evolution. Display graphs are created by identifying common leaf labels in two or more phylogenetic trees or networks.

Extension Complexity, MSO Logic, and Treewidth [PDF]
We consider the convex hull $P_{\varphi}(G)$ of all satisfying assignments of a given MSO formula $\varphi$ on a given graph $G$. We show that there exists an extended formulation of the polytope $P_{\varphi}(G)$ that can be described by $f(|\varphi ...

Nordhaus–Gaddum for treewidth [PDF]
We prove that for every graph $G$ with $n$ vertices, the treewidth of $G$ plus the treewidth of the complement of $G$ is at least $n-2$. This bound is tight.

Clique Transversal Variants on Graphs: A Parameterized-Complexity Perspective
The clique transversal problem and its variants have garnered significant attention in the last two decades due to their practical applications in communication networks, social-network theory and transceiver placement for cellular telephones.

The Treewidth of Induced Graphs of Conditional Preference Networks Is Small
Conditional preference networks (CP-nets) are recently an emerging topic as a graphical model for compactly representing ordinal conditional preference relations on multi-attribute domains.

Recent Advances in Positive-Instance Driven Graph Searching
Research on the similarity of a graph to being a tree—called the treewidth of the graph—has seen an enormous rise within the last decade, but a practically fast algorithm for this task has been discovered only recently by Tamaki (ESA 2017).

Metric Dimension Parameterized By Treewidth [PDF]
AbstractA resolving set S of a graph G is a subset of its vertices such that no two vertices of G have the same distance vector to S. The Metric Dimension problem asks for a resolving set of minimum size, and in its decision form, a resolving set of size at most some specified integer.
