A classification of rotary embeddings of multicycles
Zhaochen Ding, Zheng Guo, Luyi Liu
We classify rotary (orientably-regular) maps whose underlying graphs are multicycles. For the multicycle of length and edge-multiplicity , we determin…

Embedding a Praeger-Xu graph into a surface
Zhaochen Ding, Zheng Guo, Luyi Liu
Rotary maps (orientably regular maps) are highly symmetric graph embeddings on orientable surfaces. This paper classifies all rotary maps whose underlying graphs are Praeger-Xu gra…
