2009 On tree-partition-width by Wood
- page 1 : tree-partition-width – A graph $H$ is a partition of a graph $G$ if: each vertex of $H$ is a set of vertices of $G$ (called a bag), every evrtex of $G$ is in exactly one bag of $H$, and distinct bags $A$ and $B$ are adjacent in $H$ if and only if there is an edge of $G$ with one endpoint in $A$ and the other endpoint in $B$. The width of a partition is the maximum number of vertices in a bag. … If a forest $T$ is a partition of a graph $G$, then $T$ is a tree-partition of $G$. The tree-partition-width of $G$ … is the minimum width of a tree-partition of $G$.
