Abstract

We proof that every graph of clique-width k which does not contain the complete bipartite graph Kn,n for some n > 1 as a subgraph has tree-width at most 3k(n - 1) - 1. This immediately implies that a set of graphs of bounded clique-width has bounded tree-width if it is uniformly l-sparse, closed under subgraphs, of bounded degree, or planar.
