Structural properties of graph products
Abstract Dujmovć, Joret, Micek, Morin, Ueckerdt, and Wood established that every planar graph is a subgraph of the strong product of a graph with bounded treewidth and a path. Motivated by this result, this paper systematically studies various structural properties of cartesian, direct and strong products.

Treewidth, crushing and hyperbolic volume [PDF]
International audienceThe treewidth of a 3-manifold triangulation plays an important role in algorith-mic 3-manifold theory, and so it is useful to find bounds on the treewidth in terms of other properties of the manifold.

Edge-treewidth: Algorithmic and combinatorial properties
International audienceWe introduce the graph theoretical parameter of edge-treewidth. This parameter occurs in a natural way as the tree-like analogue of cutwidth or, alternatively, as an edge-analogue of treewidth.

On Constrained Minimum Weight Edge Covers With Applications to Emergency Planning
ABSTRACT In this paper we present a new covering problem, called Min Cost q$$ q $$‐Single Location Cover, where we are given a fixed positive integer q$$ q $$, a finite ground set J$$ J $$, an integral positive demand dj$$ {d}_j $$ for each element j∈J$$ j\in J $$, a collection 𝒥 of subsets of J$$ J $$, an integral positive cost cS$$ {c}_S $$ and an ...

A Brief Overview of Applications of Tree-Width and Other Graph Width Parameters
Graph theory, a fundamental branch of mathematics, centers on the study of networks composed of vertices (nodes) and edges, examining their paths, structures, and properties.

Phylogenetic incongruence through the lens of Monadic Second Order logic
Within the field of phylogenetics there is growing interest in measures for summarising the dissimilarity, or incongruence, of two or more phylogenetic trees. Many of these measures are NP-hard to compute and this has stimulated a considerable volume of

Dominating sets and local treewidth
It is known that the treewidth of a planar graph with a dominating set of size d is O(sqrt{d}) and this fact is used as the basis for several fixed parameter algorithms on planar graphs.

Optimal Padded Decomposition For Bounded Treewidth Graphs [PDF]
A $(β,δ,Δ)$-padded decomposition of an edge-weighted graph $G = (V,E,w)$ is a stochastic decomposition into clusters of diameter at most $Δ$ such that for every vertex $v\in V$, the probability that $\rm{ball}_G(v,γΔ)$ is entirely contained in the ...

On Treewidth and Stable Marriage
Stable Marriage is a fundamental problem to both computer science and economics. Four well-known NP-hard optimization versions of this problem are the Sex-Equal Stable Marriage (SESM), Balanced Stable Marriage (BSM), max-Stable Marriage with Ties (max-SMT) and min-Stable Marriage with Ties (min-SMT) problems.
