The tangent indicatrix germ of [X.sub.i] is the zero level set of [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII], Since K-equivalent among function germs preserves the zero-level sets of function germs, the assertion follows Theorem 16.
There exists an open dense subset O [subset] [Emb.sub.L](U, [H.sup.3.sub.1]) such that for any X [subset] O, the germ of the corresponding tangent indicatrix at any point ([x.sub.0], [y.sub.0]) [member of] U is diffeomorphic to one of the germs in the following lists.
