The graphs with only self-dual signings
✍ Frank Harary; Helene J. Kommel πŸ“‚ Article πŸ“… 1979 πŸ› Elsevier Science 🌐 English βš– 669 KB

Given a graph G, it is possible to attach positive and negative sigis to its lines only, to its points only, or to both. The resulting structu-es are called respectively signed graphs, marked graphs and nets. The dual of each such structure is obtained by changing every sign in it. We determine all

Self-dual embeddings of complete multipa

## Abstract In this paper we examine self‐dual embeddings of complete multipartite graphs, focusing primarily on __K__~__m__(__n__)~ having __m__ parts each of size __n.__ If __m__ = 2, then __n__ must be even. If the embedding is on an orientable surface, then an Euler characteristic argument show

## Abstract Regular maps are cellular decompositions of surfaces with the β€œhighest level of symmetry”, not necessarily orientation‐preserving. Such maps can be identified with three‐generator presentations of groups __G__ of the form __G__ = γ€ˆ__a, b, c__|__a__^2^ = __b__^2^ = __c__^2^ = (__ab__)^__
