Branched immersions onto compact orientable surfaces
Branched immersions onto compact orientable surfaces
In this paper smooth maps /: Mn —> Nn with a zerodimensional critical set are considered. The singularities of these maps in the case n — 2 are known to be points where / is locally topologically equivalent to z -»zd {d~ 2,3, •••)• Originally these singularities were studied in …
