Total vertex product irregularity strength of graphs
Marcin Anholcer, Azam Sadat Emadi, Doost Ali Mojdeh
Consider a simple graph . We call a labeling (\textit{total vertex}) \textit{product-irregular}, if all product degrees …
On the upper Bound of double Roman dominating function
Atieh Teimourzadeh, Doost Ali Mojdeh
A double Roman Dominating function on a graph is a function such that the following conditions hold. If , then vertex must have at lea…
The Laplacian eigenvalue 2 of bicyclic graphs
Doost Ali Mojdeh, Mohammad Habibi, Masoumeh Farkhondeh
If is a graph, its Laplacian is the difference between diagonal matrix of its vertex degrees and its adjacency matrix. A one-edge connection of two graphs and i…
Outer independent double Roman domination number of graphs
Doost Ali Mojdeh, Babak Samadi, Zehui Shao +1
A double Roman dominating function of a graph is a function having the property that for each vertex with , there exists …
Double domination and total -domination in digraphs and their dual problems
Doost Ali Mojdeh, Babak Samadi
A subset of vertices of a digraph is a double dominating set (total -dominating set) if every vertex not in is adjacent from at least two vertices in , and every…
Global offensive -alliances in digraphs
Doost Ali Mojdeh, Babak Samadi, Ismael G. Yero
In this paper, we initiate the study of global offensive -alliances in digraphs. Given a digraph , a global offensive -alliance in a digraph is a subset $S…
