完全图的指数3双嵌入

Index 3 biembeddings of the complete graphs

Juvenal F. Barajas, Timothy Sun

摘要:

证明了$24s+21$顶点上的完全图可分解为两个边不交的子图,每个子图三角化一个可定向曲面.两个曲面同胚的特殊情况解决了该曲面的广义地月问题。与以前的构造不同,这些三角嵌入对来自索引3电流图。

英文摘要:

We show that the complete graphs on $24s+21$ vertices have decompositions into two edge-disjoint subgraphs, each of which triangulates an orientable surface. The special case where the two surfaces are homeomorphic solves a generalized Earth-Moon problem for that surface. Unlike previous constructions, these pairs of triangular embeddings are derived from index 3 current graphs.
