Domination with respect to nondegenerate properties: vertex and edge removal

Vladimir D. Samodivkin — 2013

Mathematica Bohemica

In this paper we present results on changing and unchanging of the domination number with respect to the nondegenerate property 𝒫 , denoted by γ 𝒫 ( G ) , when a graph G is modified by deleting a vertex or deleting edges. A graph G is ( γ 𝒫 ( G ) , k ) 𝒫 -critical if γ 𝒫 ( G - S ) < γ 𝒫 ( G ) for any set S V ( G ) with | S | = k . Properties of ( γ 𝒫 , k ) 𝒫 -critical graphs are studied. The plus bondage number with respect to the property 𝒫 , denoted b 𝒫 + ( G ) , is the cardinality of the smallest set of edges U E ( G ) such that γ 𝒫 ( G - U ) > γ 𝒫 ( G ) . Some known results for ordinary domination and bondage numbers...

Upper bounds for the domination subdivision and bondage numbers of graphs on topological surfaces

Vladimir D. Samodivkin — 2013

Czechoslovak Mathematical Journal

For a graph property 𝒫 and a graph G , we define the domination subdivision number with respect to the property 𝒫 to be the minimum number of edges that must be subdivided (where each edge in G can be subdivided at most once) in order to change the domination number with respect to the property 𝒫 . In this paper we obtain upper bounds in terms of maximum degree and orientable/non-orientable genus for the domination subdivision number with respect to an induced-hereditary property, total domination...

Domination with respect to nondegenerate and hereditary properties

Vladimir D. Samodivkin — 2008

Mathematica Bohemica

For a graphical property 𝒫 and a graph G , a subset S of vertices of G is a 𝒫 -set if the subgraph induced by S has the property 𝒫 . The domination number with respect to the property 𝒫 , is the minimum cardinality of a dominating 𝒫 -set. In this paper we present results on changing and unchanging of the domination number with respect to the nondegenerate and hereditary properties when a graph is modified by adding an edge or deleting a vertex.
