Geometry Seminar: Saji -- Recognition criteria of Mond singularity

Singularities of map germs have long been studied, especially up to the equivalence
under coordinate changes in both source and target.  How to classify and how to
recognise a given type ? Classification is well understood, with many good references in
the literature.  Previously the method used for recognition was firstly to normalize a
given map germ and next to study its jet.  For applications however, criteria of
recognition singularities without involving normalization is more convenient.  In this
talk I shall give criteria for the recognition of singularities studied by David Mond.
