On the r-dynamic coloring of some fan graph families
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2021 In this paper, we determine the r-dynamic chromatic number of the fan graph Fm,n and determine sharp bounds of this graph invariant for four related families of graphs: The middle graph M(Fm,n), the total graph T (Fm,n), the central graph C(Fm,n) and the

Line Graphs and Middle Graphs that are Divisor Graphs
WSEAS TRANSACTIONS ON MATHEMATICS, 2020 In this paper it is determined when the line graphs and the middle graphs of some classes of graphs are divisor graphs. Complete characterizations for cycles, trees, complete graphs and complete multipartite graphs whose line graphs (middle graphs) are divisor graphs are obtained. It is also shown that the line graphs and the middle graphs of the cycle

Split Domination Number in Edge Semi-Middle Graph
Pan-American Journal of Mathematics, 2022 Let G = (p, q) be a connected graph and Me(G) be its corresponding edge semi-middle graph. A dominating set D ⊆ V [Me(G)] is split dominating set V [Me(G)] – D is disconnected.

Regular Restrained Domination in Middle Graph [PDF]
, 2023 In this paper, we introduce the new concept called regular restrained domination in middle graph.A set S ? V[M(G)] is a restrained dominating set if every vertex in V-S is adjacent to a vertex in S and another vertex in V-S.

BILANGAN DOMINASI LOKASI PADA LINE PAN GRAPH DAN MIDDLE PAN GRAPH [PDF]
, 2021 Let G is a simple, connected, and undirected graph. A set D is a subset of V. If every node of V adjacent to at least one node D, then D is a dominating set of the graph G . One of the topics from dominating set is locating dominating set. Locating
