 \nTitle: Open problems about deformations of singular holomorphic map germ
 s\n\nAbstract:\n\nThe theory of deformations of germs of holomorphic mappi
 ngs and the theory of deformations of germs of complex hypersurfaces share
  many features\, which become apparent once one knows how to translate fro
 m one to the other. But\, for any result about hypersurfaces\, the corresp
 onding result about mappings tends to be much harder to prove. In this tal
 k we will discuss open problems about singular mappings\, based on the fol
 lowing known results about isolated hypersurface singularities:\n\n· The 
 Milnor number is greater than or equal to the Tjurina number and their quo
 tient cannot exceed the dimension of the ambient space.\n\n· If two hyper
 surfaces have the same topological type\, then their Milnor numbers are eq
 ual.\n\n· Singularities cannot be split in two without giving rise to non
 -trivial homology.
