Abstract

The neighbourhood-width of a graph G=(V,E) is introduced in [F. Gurski, Linear layouts measuring neighbourhoods in graphs, Discrete Math. 306 (15) (2006) 1637-1650.] as the smallest integer k such that there is a linear layout @f:V-{1,...,|V|} such that for every 1=i. In this paper we show first bounds for the neighbourhood-width of general graphs, caterpillars, trees and grid graphs and give applications of the layout parameter neighbourhood-width in graph drawing and VLSI design.
