WebMar 12, 2024 · We define C, c, D, and M_0 as in the proof of Theorem 1. If D is an edge-dominating set of G, then D is the edge-dominating set as desired. Otherwise, there exists at least one edge e such that d_G (e,D)\ge 1. Since G is 2-connected, there is an open ear F with length at least 3 containing e. WebJan 24, 2024 · The vertex-edge dominating set problem was introduced by Peters [] and then studied further by different researchers.In particular, bounds on the vertex-edge domination number in several graph classes were studied in [3, 14,15,16, 20], vertex-edge degrees and vertex-edge domination polynomials of different graphs were discussed in …
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. WebApr 10, 2024 · The v-number of a graded ideal is an algebraic invariant introduced by Cooper et al., and originally motivated by problems in algebraic coding theory. In this paper we study the case of binomial edge ideals and we establish a significant connection between their v-numbers and the concept of connected domination in graphs. More …
WebOct 15, 2024 · A natural connection between the domination number and the edge domination number of a graph G becomes apparent when considering the line graph L (G) of G. Since a maximal matching M in G is a maximal independent set in L (G), the edge domination number γ e (G) of G equals the independent domination number i (L (G)) of … WebThe concept of edge domination was introduced by Mitchell and Hedetniemi and it is explored by many researchers. Arumugam and Velammal have discussed the edge …
WebThe majority of graph theory research on parameters involved with domination, independence, and irredundance has focused on either sets of vertices or sets of edges; for example, sets of vertices that dominate all other vertices or sets of edges that dominate all other edges. There has been very little research on ``mixing'' vertices and edges. We …
