On the Signed Complete Graphs with Maximum Index
N. Kafai, F. Heydari, N. Jafari Rad +1
Let be a signed complete graph whose negative edges induce a subgraph . The index of is the largest eigenvalue of its adjacency matrix. In this paper we stud…
On The Double Roman bondage numbers of Graphs
N. Jafari Rad, H. R. Maimani, M. Momeni +1
For a graph , a double roman dominating function (DRDF) is a function having the property that if for some vertex , then…
Total domination in cubic Knödel graphs
Doost Ali Mojdeh, Seyed Reza Musawi, Esmaeil Nazari +1
A subset of vertices of a graph is a \textit{dominating set} if for each , is adjacent to some vertex . The \textit{dominating number}, $γ…
Results on the intersection graphs of subspaces of a vector space
N. Jafari Rad, S. H. Jafari
For a vector space the \emph{intersection graph of subspaces} of , denoted by , is the graph whose vertices are in a one-to-one correspondence with proper nontrivial s…
Bounds on the 2-rainbow domination number of graphs
Yunjian Wu, N. Jafari Rad
A {\it 2-rainbow domination function} of a graph is a function that assigns to each vertex a set of colors chosen from the set , such that for any , $f(…
