摘要:计算了一个具体图类日。的交叉数.然后研究了一个五点图G和P,路的联图G V Pn,并用归纳假设法证明了这个五点图和路的联图的交叉数Cr(G V Pn),即当n≥2时,Cr(G V Pn)=4[n/2][(n-1)/2]+[n/2]+1.
摘要:計算瞭一箇具體圖類日。的交扠數.然後研究瞭一箇五點圖G和P,路的聯圖G V Pn,併用歸納假設法證明瞭這箇五點圖和路的聯圖的交扠數Cr(G V Pn),即噹n≥2時,Cr(G V Pn)=4[n/2][(n-1)/2]+[n/2]+1.
적요:계산료일개구체도류일。적교차수.연후연구료일개오점도G화P,로적련도G V Pn,병용귀납가설법증명료저개오점도화로적련도적교차수Cr(G V Pn),즉당n≥2시,Cr(G V Pn)=4[n/2][(n-1)/2]+[n/2]+1.
The crossing number of graph H. is studied and the crossing number of the join graph G V P,, of a 5-vertex graph G and path Pn is considered. By using inductive princeple, the crossing number of the join of G and Pn is shown as Cr(G V Pn)=4[n/2][(n-1)/2]+[n/2]+1≥2.
