P-图与它的结构

Graphs and Its Structure

利用P-集合,提出P-图,P-图是由内P-图GF-与外P-图GF构成的图对;或者(GF-,GF)是P-图,P-图具有动态特性.给出P-图的结构,给出P-图与普通图的关系;在一定条件下,P-图能回到普通图的"原点".P-图是普通图论中的一个新的研究方向与研究分支.

By using P- sets, packet graphs called P- graphs are presented, which are composed of internal packet graphs and outer packet graphs. That is to say, （G^F- ,G^F） are P - graphs. P - graphs have dynamic characteristics. The structure of P- graphs is given and the relations between P- graphs and com- mon graphs are given. Under certain conditions, P- graphs can return to the origin of common graphs. P - graphs are new research direction and research branch in graph theory.
