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. Label the neighbors lying on pendent paths of u as u_1,u_2,\ldots , … See more Suppose T is a tree and u is a p-major vertex with a pendent path P_{\ell +1}(\ell \ge 1). If T' is the graph obtained from T by replacing P_{\ell +1} with a pendent edge, then F_{t}(T)=F_{t}(T') … See more [23] Suppose that T is a tree and u is an end-major vertex of T with d_p(u)=\ell (\ge 2). If T_1 is a tree by removing an A_{\ell } associated with u … See more Suppose T is a non-trivial tree, v\in V(T) with d(v)=1, and S be an F-set of T. If v\not \in S, then there is a vertex x\in S for which S'=(S\backslash {\{x\}})\cup {\{v\}} is an F-set of T.
