If T_1 is a tree and u is vertex of T_1 with d(u)\ge 2. Then T_2 is a new tree obtained from T_1 by connecting u with some vertex of a path with degree two. The process from T_1 to T_2 is called as Operation I. For a given tree T(\cong P_r(r\ge 3)), we may define an A_2-sequence T_{1}(\cong T) \preceq T_{2} \preceq … See more Suppose T is a tree and u\in V(T) is a p-major vertex with d_{P}(u)=\ell \ge 3.

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. high kelling churchWebMar 14, 2024 · The number of cases in total: ( 12 4) = 495 The number of ways three trees happen to be on the same row, column or diagonal: 14 ways.
