Connectivity, graph minors, and subgraph multiplicity
It is well known that any planar graph contains at most O(n) complete subgraphs. We extend this to an exact characterization: G occurs O(n) times as a subgraph of any planar graph, if and only if G is three-connected. We generalize these results to similarly characterize certain other minor-closed families of graphs; in particular, G occurs O(n) times as a subgraph of the Kb,c-free graphs, b ≥ ...
متن کاملGraph Minors
For a given graph G and integers b, f ≥ 0, let S be a subset of vertices of G of size b + 1 such that the subgraph of G induced by S is connected and S can be separated from other vertices of G by removing f vertices. We prove that every graph on n vertices contains at most n/ b+f b such vertex subsets. This result from extremal combinatorics appears to be very useful in the design of several e...
متن کاملTreewidth and graph minors
We shall touch upon the theory of Graph Minors by Robertson and Seymour. This theory gives a very general condition under which a graph problem has a polynomial time algorithm (though the algorithms that come out of the theory are often not practical). We shall review a small part of this theory, and illustrate how dynamic programming can be used to solve some NP-hard problems on restricted cla...
متن کاملGraph minors and linkages
Bollobás and Thomason showed that every 22k-connected graph is k-linked. Their result used a dense graph minor. In this paper we investigate the ties between small graph minors and linkages. In particular, we show that a 6-connected graph with a K− 9 minor is 3-linked. Further, we show that a 7-connected graph with a K− 9 minor is (2, 5)-linked. Finally, we show that a graph of order n and size...
متن کاملStrong Subgraph $k$-connectivity
Generalized connectivity introduced by Hager (1985) has been studied extensively in undirected graphs and become an established area in undirected graph theory. For connectivity problems, directed graphs can be considered as generalizations of undirected graphs. In this paper, we introduce a natural extension of generalized k-connectivity of undirected graphs to directed graphs (we call it stro...
