Abstract

Let F:(C2,0)(Cn,0)F:(\mathbb{C}^2,0)\to (\mathbb{C}^n,0) be the germ of a finite map and (X,0)(X,0) be its image. We will in this article using the topology of the link show that (X,0)(X,0) has to be a quotient singularity if it is normal and describe the possible topological types. Including a discussion of the groups and examples of how to construct a map to a given topology. We will also discuss the case when the image is not normal.
