Full domination in graphs

Robert C. BrighamGary ChartrandRonald D. DuttonPing Zhang — 2001

Discussiones Mathematicae Graph Theory

For each vertex v in a graph G, let there be associated a subgraph H v of G. The vertex v is said to dominate H v as well as dominate each vertex and edge of H v . A set S of vertices of G is called a full dominating set if every vertex of G is dominated by some vertex of S, as is every edge of G. The minimum cardinality of a full dominating set of G is its full domination number γ F H ( G ) . A full dominating set of G of cardinality γ F H ( G ) is called a γ F H -set of G. We study three types of full domination in graphs: full...

Resolving domination in graphs

Robert C. BrighamGary ChartrandRonald D. DuttonPing Zhang — 2003

Mathematica Bohemica

For an ordered set W = { w 1 , w 2 , , w k } of vertices and a vertex v in a connected graph G , the (metric) representation of v with respect to W is the k -vector r ( v | W ) = ( d ( v , w 1 ) , d ( v , w 2 ) , , d ( v , w k ) ) , where d ( x , y ) represents the distance between the vertices x and y . The set W is a resolving set for G if distinct vertices of G have distinct representations with respect to W . A resolving set of minimum cardinality is called a minimum resolving set or a basis and the cardinality of a basis for G is its dimension dim G . A set S of vertices in G is a dominating set...
