WebMar 22, 2024 · In this paper, we study the zero forcing number of trees. Let T be a tree with at least two vertices. We show that \Delta (T)-1\le Z (T)\le r (T)-1, where \Delta (T) and r ( T) are the maximum degree and the number of pendant vertices of T, respectively. As a consequence, we obtain that Z (L (T))\ge Z (T), where L ( T) is the line graph of T. dan armstrong blue clipper schematic
