Tree-Partitions with Small Bounded Degree Trees

Combinatorics 2023-07-31 v2

Abstract

A "tree-partition" of a graph GG is a partition of V(G)V(G) such that identifying the vertices in each part gives a tree. It is known that every graph with treewidth kk and maximum degree Δ\Delta has a tree-partition with parts of size O(kΔ)O(k\Delta). We prove the same result with the extra property that the underlying tree has maximum degree O(Δ)O(\Delta) and O(V(G)/k)O(|V(G)|/k) vertices.
