Description

The largest part of an integer composition.

chromatic difference sequence

Description

The chromatic difference sequence of a graph.
Let

$G$ be a simple graph with chromatic number

$\kappa$ . Let

$\alpha_m$ be the maximum number of vertices in a

$m$ -colorable subgraph of

$G$ . Set

$\delta_m=\alpha_m-\alpha_{m-1}$ . The sequence

$\delta_1,\delta_2,\dots\delta_\kappa$ is the chromatic difference sequence of

$G$ .
All entries of the chromatic difference sequence are positive:

$\alpha_m > \alpha_{m-1}$ for

$m < \kappa$ , because we can assign any uncolored vertex of a partial coloring with

$m-1$ colors the color

$m$ . Therefore, the chromatic difference sequence is a composition of the number of vertices of

$G$ into

$\kappa$ parts.

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.
