Description

The cardinality of a minimal edge-isolating set of a graph. Let

$\mathcal F$ be a set of graphs. A set of vertices

$S$ is

$\mathcal F$ -isolating, if the subgraph induced by the vertices in the complement of the closed neighbourhood of

$S$ does not contain any graph in

$\mathcal F$ . This statistic returns the cardinality of the smallest isolating set when

$\mathcal F$ contains only the graph with one edge.

Matching statistic: St001395

Description

The number of strictly unfriendly partitions of a graph. A strictly unfriendly partitions of a graph is a two-colouring of its vertices such that every vertex has more neighbours of the other colour than of the same colour. This statistic returns the number of strictly unfriendly partitions, up to switching the colours. For example, the complete graph on four vertices has three strictly unfriendly partitions: the three set partitions of the vertices into two blocks of size two.

Description

The order of the largest clique of the graph. A clique in a graph

$G$ is a subset

$U \subseteq V(G)$ such that any pair of vertices in

$U$ are adjacent. I.e. the subgraph induced by

$U$ is a complete graph.

Matching statistic: St000098

Description

The hull number of a graph. The convex hull of a set of vertices

$S$ of a graph is the smallest set

$h(S)$ such that for any pair

$u,v\in h(S)$ all vertices on a shortest path from

$u$ to

$v$ are also in

$h(S)$ . The hull number is the size of the smallest set

$S$ such that

$h(S)$ is the set of all vertices.

Description

The monophonic hull number of a graph. The monophonic hull of a set of vertices

$M$ of a graph

$G$ is the set of vertices that lie on at least one induced path between vertices in

$M$ . The monophonic hull number is the size of the smallest set

$M$ such that the monophonic hull of

$M$ is all of

$G$ . For example, the monophonic hull number of a graph

$G$ with

$n$ vertices is

$n$ if and only if

$G$ is a disjoint union of complete graphs.
