Arnold's classification scheme. For example, decide whether a singularity is one of the Kleinian (also refered to as simple or ADE) singularities which are given by the following normal forms: Ak: x1k+1 + x22 + x32 + ... + xn2 , k >= 1 Dk: x1(x1k-2 + x22) +x32 + ... + xn2 , k >= 4 E6: x14 + x23 + x32 + ... + xn2 E7: x2(x13 + x22) +x32 + ... + xn2 E8: x15 + x23 + x32 + ... + xn2 SINGULAR Code
