Abstract

Beineke, Harary, and Ringel discovered a formula for the minimum genus of a torus in which the n-dimensional hypercube graph can be embedded. We give a new proof of the formula by building this surface as a union of certain faces in the hypercube’s 2-skeleton. For odd dimension n, the entire 2-skeleton decomposes into (n1)/2 copies of the surface, and the intersection of any two copies is the hypercube graph.

Hypercube属的新观点

摘要

Beineke,Harary和Ringel发现了一个圆环的最小类的公式,其中可以嵌入n维超立方体图。通过将该表面构造为超立方体的2骨架中某些面的并集,我们为公式提供了新的证明。对于奇数维n,整个2骨架分解为ñ-1个/2个 曲面的两个副本,并且任何两个副本的交点都是超立方体图。
