摘    要:
Taniyam在文[5]中构造了一个平面图有Tn的正则投射,其中平面图是由正五边形所构造的。推广了Taniyam的结果,证明了由任意奇数边(≥5)正多边形所构造的平面图都会有一个有Tn的正则投射,另外,对于这些平面图,还构造了一种新的有Tn的正则投射。

关 键 词:正则投射  有纽结/链环的  有Tn的

Knot- inevitable regular projections of planar graphs

Abstract:
For any integer n, Taniyama and Tsukamoto described a Tn - inevitable regular projection of a planar graph in [5], where the planar graph is constructed by regular pentagons. The authors extend the conclusion and show that all of the planar graphs constructed by regular polygons with odd number (≥5 ) of edges also have Tn - inevitable regular projections. Moreover, a new Tn - inevitable regular projection of such planar graphs and some related results are also given.
Keywords:regular projection  knot/link-inevitable  Tn-inevitable
