Sandra Albrechtsen, Reinhard Diestel, Ann-Kathrin Elm +4
It is an easy observation that if a graph~ admits a path-decomposition whose parts have small radius, then contains no large subdivision of or as a (quasi-)g…

Reinhard Diestel, Raphael W. Jacobs, Paul Knappe +1
We show that a graph contains a large wall as a strong immersion minor if and only if the graph does not admit a tree-cut decomposition of small 'width', which is measured in terms…
