We give a polynomial algorithm which decides the integer solvability of multicommodity flow problems where the union of "capacity-" and "demand-edges" forms a planar graph, and the number of demand edges is bounded by a prefixed integer \(k\). This problem was solved earlier for \(k=2\) by Seymour a

Let P(n) be the class of all connected graphs having exactly n ~> 1 negative eigenvalues (including their multiplicities). In this paper we prove that the class P(n) contains only finitely many so-called canonical graphs. The analogous statement for the class Q(n) of all connected graphs having exac
For every positive integer c , we construct a pair G, , H, of infinite, nonisomorphic graphs both having exactly c components such that G, and H, are hypomorphic, i.e., G, and H, have the same families of vertex-deleted subgraphs. This solves a problem of Bondy and Hemminger. Furthermore, the pair G
