Bounds on the spectral radius of a type of tree graphs 一类树图谱半径的界
Especially , the adjacent tree graph and line graph are both included as special cases of our generalization 特别,邻接树图和线图是我们推广的特殊情况。
Introduced in this paper is the forest graph of a connected graph which is a generalization of the tree graph 摘要本文中引进了连通图的森林图,它是树图的推广。
( 2 ) basic graph of quasi - fuzzy graph matriod : basic graph is extending tree graph , and it is an important tool by which matroid is studied 2 )准模糊图拟阵的基图:基图是树图概念的推广,是研究拟阵的重要工具。
Nowadays , concerning the relaxed game chromatic number of tree , out - erplanar and partial k - tree graph have been studied by many researchers home and abroad , this paper studies further the relaxed game chromatic number of trees 如今,关于树,外平面图及偏k -树的松弛竞赛染色已引起众多学者的研究,本文主要研究森林的松弛竞赛色数。
