Abstract
In the article, we show that the germ of a finite morphism of smooth surfaces is rigid if and only if the germ of its branch curve has an ADE singularity type. We establish a correspondence between the set of rigid germs of finite morphisms and the set of Belyi rational functions f is an element of (Q) over bar (z).Funding Information
