The k-power graph of a graph G is a graphwith the same vertex set as G, in that two vertices are adjacent if and only if, there is a path between them in G of length at most k. A k-treepower graph is the k-power graph of a tree, a k-leaf-power graph is the subgraph of some k-tree-power graph induced by the leaves of the tree. We show that (1) every k-tree-power graph has NLC-width at most k + 2...
