Description
The bandwidth of a graph.
The bandwidth of a graph is the smallest number k such that the vertices of the graph can be
ordered as v1,…,vn with k⋅d(vi,vj)≥|i−j|.
We adopt the convention that the singleton graph has bandwidth 0, consistent with the bandwith of the complete graph on n vertices having bandwidth n−1, but in contrast to any path graph on more than one vertex having bandwidth 1. The bandwidth of a disconnected graph is the maximum of the bandwidths of the connected components.
Map
to threshold graph
Description
The threshold graph corresponding to the composition.
A threshold graph is a graph that can be obtained from the empty graph by adding successively isolated and dominating vertices.
A threshold graph is uniquely determined by its degree sequence.
The Laplacian spectrum of a threshold graph is integral. Interpreting it as an integer partition, it is the conjugate of the partition given by its degree sequence.
Map
line graph
Description
The line graph of a graph.
Let G be a graph with edge set E. Then its line graph is the graph with vertex set E, such that two vertices e and f are adjacent if and only if they are incident to a common vertex in G.
Map
complement
Description
The complement of a graph.
The complement of a graph has the same vertices, but exactly those edges that are not in the original graph.
