Abstract.
Our aim is to give discrete versions for some classical theorems that are well-known in Riemann surface theory.
In particular, we will be concentrated on different versions of the Hurwitz 84(g−1)-theorem, the Wiman theorem, the Maclachlan-Accola theorem and some recent results obtained by AraKawa.
The main subjects of investigation will be graphs and finite group acting harmonically on them.
