Domino Treewidth

Journal of Algorithms, 1997
Summary: We consider a special variant of tree-decompositions, called domino tree-decompositions, and the related notion of domino treewidth. In a domino tree- decomposition, each vertex of the graph belongs to at most two nodes of the tree. We prove that for every \(k\), \(d\), there exists a constant \(c_{k,d}\) such that a graph with treewidth at ...

The treewidth of line graphs

open access: yesJournal of Combinatorial Theory Series B, 2018
The treewidth of a graph is an important invariant in structural and algorithmic graph theory. This paper studies the treewidth of line graphs. We show that determining the treewidth of the line graph of a graph $G$ is equivalent to determining the minimum vertex congestion of an embedding of $G$ into a tree.
