Linked tree-decompositions into finite parts
Sandra Albrechtsen, Raphael W. Jacobs, Paul Knappe +1
We prove that every graph which admits a tree-decomposition into finite parts has a rooted tree-decomposition into finite parts that is linked, tight and componental. As an applica…

Counterexamples regarding linked and lean tree-decompositions of infinite graphs
Sandra Albrechtsen, Raphael W. Jacobs, Paul Knappe +1
Kriz and Thomas showed that every (finite or infinite) graph of tree-width admits a lean tree-decomposition of width . We discuss a number of counterexamples…
