摘要:

利用组合的方法研究路与路、 路与圈笛卡尔积图的树核度. 特别地, 给出了路与路、 路与圈笛卡尔积图树核度的精确值, 并刻画了笛卡尔积图树核度与原图树核度间的关系.

关键词: 树核度, 树核, 笛卡尔积, 路,

Abstract:

Using the combined method, we investigated the treecoritivity of Cartesian products graphs of path and path, and path and cycle. In particular, we gave the exact value of treecoritivities for Cartesian products of path and path, and path and cycle, and characterized a relation between the treecoritivity of Cartesian product and that of its original graphs.

Key words: treecoritivity, treecore, Cartesian product, path, cycle
