A classification of regular maps with Euler characteristic $- pq$

Xiaogang Li, Yao Tian

In this paper, we give a classification of regular maps with Euler characteristic $- pq$ for distinct primes $q > p \geq 5$ . This together with previous classification of regular maps…

A classification of regular maps with Euler characteristic $- p^{4}$ for a prime $p \geq 5$

Xiaogang Li, Yao Tian

A map is a cellular decomposition of a closed surface. In the framework of classifying all regular maps by their supporting surface, it is an open problem to find all closed surfac…
