We generalize the concept of tree-width to directed graphs and prove that every directed graph with no ``haven'' of large order has small tree-width. Conversely, a digraph with a large haven has large tree-width. We also show that the Hamilton cycle problem and other NP-hard problems can be solved i

We show that (1) the recognition of tree-width bounded graphs and (2) the decidability of graph properties--which are defined by finite equivalence relations on \(h\)-sourced graphs-on tree-width bounded graphs belong to the complexity class LOGCFL. This is the lowest complexity class known for thes
## Abstract We prove that every graph of circumference __k__ has treeβwidth at most __k__βββ1 and that this bound is best possible. Β© 2003 Wiley Periodicals, Inc. J Graph Theory 43: 24β25, 2003
Let G be a simple graph with n vertices and tw(G) be the tree-width of G. Let (G) be the spectral radius of G and (G) be the smallest eigenvalue of G. The join GβH of disjoint graphs of G and H is the graph obtained from G + H by joining each vertex of G to each vertex of H . In this paper, several
In 1971, Chartrand, Geller, and Hedetniemi conjectured that the edge set of a planar graph may be partitioned into two subsets, each of which induces an outerplanar graph. Some partial results towards this conjecture are presented. One such result, in which a planar graph may be thus edge partitione
It is well known that on classes of graphs of bounded tree-width, every monadic second-order property is decidable in polynomial time. The converse is not true without further assumptions. It follows from the work of Robertson and Seymour, that if a class of graphs K has unbounded tree-width and is
