D.6.3 arnoldclassify_lib

Library:
arnoldClassify.lib
Purpose:
Arnol'd Classifier of Singularities
Author:
Eva Maria Hemmerling, ehemmerl@rhrk.uni-kl.de

Overview:
A library for classifying isolated hypersurface singularities from the list of V.I. Arnol'd w.r.t. right equivalence up to corank 2. The method relies on Baciu's list of Milnor codes and Newton's rotating ruler method to distinguish the Y- and Z- singularities.
