Criteria for singularities for mappings from two-manifold to the plane. The number and signs of cusps
Iwona Krzyżanowska , Aleksandra Nowel
AbstractLet M ⊂ Rn+2 be a two-dimensional complete intersection. We show how to check whether a mapping f: M → R2 is 1-generic with only folds and cusps as singularities. In this case we give an effective method to count the number of positive and negative cusps of a polynomial f, using the signatures of some quadratic forms. © 2017, Tokyo Institute of Technology.
