    • On total vertex-edge domination 

      Şahin, Bünyamin; Şahin, Abdulgani (Işık University Press, 2019)
      In this paper we obtain an improved upper bound of total vertex edgedomination number of a tree. If T is a connected tree with order n, then γͭᵥₑ(T) ≤ m/3 with m = 6[ n/6] and we characterize the trees attaining this upper ...
