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.
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.
