中文摘要: | ||||
直接从四色问题出发,建立图论的另外一个新体系.在提出区域、边界线、结点等定义,对复杂地图进行分层简化后,得到体系的3个基本定理,又用链路这一工具,证明任意有限个区域地图的四色解存在并给出了求解方法. | ||||
英文摘要: | ||||
Another new system of graph theory is established directly from four-color problem. By defining the region, boundary line, node, etc., after breaking down the complicated map into several connected single-layer subgraphs and simplifying them, three fundamental theorems of this system are obtained. And using chain, the solution existence and searching method of four-color problem related to any map with limited regions are given. | ||||
