Injective coloring of central graphs

Mirdamad, Shahrzad Sadat; Mojdeh, Doost Ali (Işık University Press, 2026-03-01)

For a given graph G = (V (G), E(G)), researchers have introduced different colorings based on the distances of the vertices. An injective coloring of a graph G is an assignment of colors to the vertices of G such that no ...
Total global dominator chromatic number of graphs

Askari, Saeid; Mojdeh, Doost Ali; Nazari, Esmaeil (Işık University Press, 2022)

Let G = (V, E) be k-colorable (k-vertex colorable) graph and Vi ⊆ V be the class of vertices with color i. Then we assume that f = (V1, V2, · · · , Vk) is a coloring of G. A vertex v ∈ V (G) is a dominator of f if v dominates ...
Upper bounds for covering total double Roman domination

Mojdeh, Doost Ali; Teymourzadeh, Atieh (Işık University Press, 2023-07)

Let G = (V, E) be a finite simple graph where V = V (G) and E = E(G). Suppose that G has no isolated vertex. A covering total double Roman dominating function (CT DRD function) f of G is a total double Roman dominating ...
