WebMar 24, 2024 · Abstract. We consider the problem of reducing the (semi)total domination number of a graph by one by contracting edges. It is known that this can always be done with at most three edge contractions and that deciding whether one edge contraction suffices is an NP-hard problem. manfaat wardah lightening day cream

WebCONNECTED DOMINATION IN GRAPHS AND V-NUMBERS OF BINOMIAL EDGE IDEALS 5 Remark 2.2. Since P∅(G) does not contain monomials, it follows that PS(G) ⊆ P∅(G) for every S. Thus, by Theorem 2.1, P∅(G) is a minimal prime of JG.In particular, when G is connected, WebA vertex subset D of G is a dominating set if every vertex in V(G)\D is adjacent to a vertex in D. A dominating set D is independent if G[D], the subgraph of G induced by D, contains … WebJan 13, 2024 · The dominating theory has received considerable attention in recent years for its strong applicability.
