Independent vertices in graph theory

WebA central vertex of a graph is a vertex with minimum eccentricity. The center of a graph G, denoted Z(G), is the subgraph induced on the set of central vertices of G. In an arbitrary graph G, the center Z(G) can be anything from a single vertex to all of G. Web24 mrt. 2024 · A graph H is an induced minor of a graph G if H can be obtained from G by vertex deletions and edge contractions. We show that there is a function f ( k , d ) = O ( k 10 + 2 d 5 ) so that if a graph has treewidth at least f ( k , d ) and maximum degree at most d, then it contains a k × k-grid as an induced minor.
