Title Criteria for cuspidal Sk singularities and their applications
Author Kentaro Saji
We give useful criteria for S1± singularities in the Mond classification table, and cuspidal Sk± singularities. As applications, we give a simple proof of a result given by Mond and a characterization of cuspidal Sk± singularities for the composition of a cuspidal edge and a fold map indicated by Arnol'd for the case k=1.
Keywords singularities, criteria, Mond singularity, wave front
