We compute the generating function for triangulations on a cylinder, with the restriction that all vertices belong to its boundary and that the intersection of a pair of different ...

Abstract. We show that the tree-width of a graph can be defined without reference to graph vertices, and hence the notion of tree-width can be naturally extended to matroids. (This...

For a tree T and an integer k ≥ 1, it is well known that the k-th power T k of T is strongly chordal and hence has a strong elimination ordering of its vertices. In this note we...
