摘要
芭蕉扇T<sub>n</sub>指在扇F<sub>n</sub>=P<sub>n</sub>(?)K<sub>1</sub>的轴K<sub>1</sub>上悬挂一条边所得的图,该边叫T<sub>n</sub>的柄,P<sub>n</sub>上的边叫缘边,其余边叫辐。芭蕉扇细分图T<sub>n</sub><sup>*</sup>是T<sub>n</sub>的缘边各剖分一次所得的图。本文证明了芭蕉扇细分图T<sub>2</sub><sup>*</sup>是模和图,且σ(T<sub>n</sub><sup>*</sup>)(?)=2,n=2、3,≤2。
Palm-leaf fan T_n is a graph of adding a hung side in the axis K_1 of fan F_n=P_n V K_1,and this edge is called the haddle of T_n,the edges on the P_n are named fringe,the others are named the spoke.This paper proves that (?) is the mod sum graph andσ(?)=1,n=2、3,≤2,n≥4
