宽度和边缘收缩

Clique-width and edge contraction

Bruno Courcelle

摘要:

我们证明了边收缩不保持一组图有界宽度的性质。这一性质通过边的收缩来保持,边的一端是2度的顶点。

英文摘要:

We prove that edge contractions do not preserve the property that a set of graphs has bounded clique-width. This property is preserved by contractions of edges, one end of which is a vertex of degree 2.
