【 摘 要 】
All graphs in this paper are a connected graph, denoted by G = (V, E).The open neighbourhood of a vertex v of a graph G is the set N(v) consisting of all vertices adjacent to v in G. For D ⊂ V(G), we define D = V(G)\D, a set D ⊂ V(G) is called a dominating set of G if for every vertex in D has at least one neighbour in D, N(v) ∩ D ≠ for every u ∈ D The minimum cardinality of all dominating set in G, is the domination number, denoted by γ(G). A set D ⊂ V(G) is called a super dominating set of G if for every vertex u ∈ D, there is exists v ∈ D such that N(v) ∩ D = {u}. The super domination number of G is the minimum cardinality among all super dominating sets in G, denoted by γsp(G). In this paper, we investigate the super domination number of unicyclic graphs namely (m, n)-tadpole graph, n-pan graph, sun graphs, cycle with two neighbour pendant vertex, and cartepillar with adding one edge.【 预 览 】
