Forbidden minors characterization of partial 3-trees. (English) Zbl 0701.05016
A partial k-tree is a subgraph of a graph that can be reduced to the complete graph of order k by a sequence of operations each being a removal of a degree k vertex with completely connected neighbours. In the paper the class of partial 3-trees is characterized by its set of four minimal forbidden minors.
