Tangle-tree duality: in graphs, matroids and beyond
Reinhard Diestel, Sang-il Oum
We apply a recent duality theorem for tangles in abstract separation systems to derive tangle-type duality theorems for width-parameters in graphs and matroids. We further derive a…

Tangle-tree duality in abstract separation systems
Reinhard Diestel, Sang-il Oum
We prove a general width duality theorem for combinatorial structures with well-defined notions of cohesion and separation. These might be graphs and matroids, but can be much more…
