On rigid germs of finite morphisms of smooth surfaces
Vik. S. Kulikov Steklov Mathematical Institute of Russian Academy of Sciences, Moscow, Russia
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 $f\in\overline{\mathbb Q}(z)$.
Bibliography: 10 titles.
Keywords:
rigid germs of finite morphisms, Belyi functions.
