内容摘要:
A (topological) map is a cellular decomposition of a closed surface. A common way to describe maps is to view them as 2-cell embeddings of graphs. An orientable map is called regular if its group of orientation preserving automorphisms acts arc-regular. Regular Cayley Maps are regular embeddings of Cayley graphs.
Recently, regular Cayley maps of cyclic groups and dihedral groups have been classified. Then a nature question is to classify regular Cayley maps of elementary abelian p-groups. In this talk, a complete classification of regular Cayley maps of elementary abelian p-groups will be given and moreover, the number of these maps and their genera will be enumerated.
