Morsification of totally real singularities of type (3,k)

A morsification of a real plane singularity is a real deformation with the maximal possible number of hyperbolic nodes. Morsifications are an important tool for the study of Dynkin diagrams, monodromy, topology of the singularity link and other characteristics of singularities. In this talk I will address the problem of isotopy classification of morfisications of totally real singularities of type (3,k). I will show how to obtain this classification by combinatorial means via dessins d'enfants and how it can be encoded by wiring diagrams. I will also described the classification of these morsifications up to Reidemeister moves.
