Title: Multi – Singularities of Planar Maps

Abstract:
The results and methods of my master thesis “Multi – Singularities of Planar Maps” will be presented. We classify, up to right – left – equivalence, normal forms of multi – germs of smooth maps from the plane to the plane up to codimension 3. Furthermore, we determine several geometric invariants for each normal form. The approach is by application of well established results regarding classificaiton of map – germs such as complete transversals, Mather’s lemma and finite determinacy results.
