摘要
可定向顶点原始完整映射是将完整图嵌入可定向曲面的双胞嵌入，使得该映射的自变群原始地作用于其顶点集。本文主要研究枚举可定向顶点原始完整映射的问题。对于给定的整数 n，我们推导出具有 n 个顶点的不同此类映射的数量。此外，我们还得到了具有 n 个顶点的非同构可定向顶点原始完整映射的数量的明确公式。
An orientable vertex primitive complete map is a two-cell embedding of a complete graph into an orientable surface such that the automorphism group of this map acts primitively on its vertex set. The paper is devoted to the problem of enumerating orientable vertex primitive complete maps. For a given integer n, we derive the number of different such maps with n vertices. Furthermore, we obtain explicit formulas for the numbers of non-isomorphic orientable vertex primitive complete maps with n vertices.
