On a disparity between relative cliquewidth and relative NLC-width
Cliquewidth and NLC-width are two closely related parameters that measure the complexity of graphs. Both cliqueand NLC-width are defined to be the minimum number of labels required to create a labelled graph by certain terms of operations. Many hard problems on graphs become solvable in polynomial-time if the inputs are restricted to graphs of bounded cliqueorNLC-width. Cliquewidth andNLC-width...
متن کاملThe NLC-width and clique-width for powers of graphs of bounded tree-width
The k-power graph of a graph G is a graphwith the same vertex set as G, in that two vertices are adjacent if and only if, there is a path between them in G of length at most k. A k-treepower graph is the k-power graph of a tree, a k-leaf-power graph is the subgraph of some k-tree-power graph induced by the leaves of the tree. We show that (1) every k-tree-power graph has NLC-width at most k + 2...
متن کاملOn switching classes, NLC-width, cliquewidth and treewidth
In this paper we consider a connection between switching (of undirected graphs), and the notions of NLC-width, cliquewidth and treewidth. In particular, we show that the NLC-widths and the cliquewidths of two graphs in a switching class are at most a constant factor apart (2 for the former, 4 for the latter). A similar result can be shown not to hold for treewidth: it is easy to find a switchin...

We demonstrate that the process e + e − → tth at the NLC provides a powerful tool for extracting the tt (Yukawa) couplings of the h. In combination with the e + e − → Zh process , an accurate determination of the ZZ coupling of the h is also possible. The resulting ability to distinguish different models of the Higgs sector is illustrated by detailed studies for two-Higgs-doublet models. In ext...
