All the results we obtain are effective, in the sense that there is an efficient hefsz that puts any plane branch into its normal form and it is easy to recognize whether two plane branches under normal form are equivalent or not.

Let f be in the maximal ideal M2 of O2 and irreducible. AmazonGlobal Ship Orders Internationally. Amazon Second Chance Pass it on, trade it in, give it a second life. In order to have a geometric interpretation of our objects, we will adopt the analytic point of view. Explore the Home Gift Guide.

The strength of our method stems in the conjugation of these two tools that allows, via the existence of some differentials, to control each step of the Complete Transversal algorithm, giving explicitly all possible normal forms and conditions for the analytic equivalence of germs in normal forms.

The reader who desires to find all the known results quoted in this section is invited to consult [6], where they are gathered with their proofs. East Dane Designer Men’s Fashion. The whole process has been implemented3.

In this paper, we show how one can break the complexity of the mod- uli space by stratifying the given equisingularity class by means of a good numerical invariant that separates branches into finitely many types, such that analytic equivalence is each stratum is manageable.

We begin with a proposition that will give us the recursion step. Now, to prove that abrajo two Puiseux parametrizations are A-equivalent, then they are conjugate under homothety, it will be sufficient to prove that if two e Puiseux parametrizations are A-equivalent, then they are equal, because the e A-action is decomposed into the A-action and the H-action.

English Choose a language for shopping. Is the above theorem true without the assumption of the genericity on the coefficients of the parametrizations?

Let us recall a special case of the Complete Transversal Theorem of [2], adapted to our use: This done, the analytic equivalence hdfez to verify homothety, which is trivial. So, the analytic classification of plane branches reduces to the A-classification of parametrizations, which we are going to undertake in this paper.

Ebey and Zariski cf. These sets are invariant under A-equivalence, as we show below. To this respect, in the introduction of [11], Zariski wrote: If you are a seller for this product, would you like to suggest updates through seller support?

Enter the email address you signed up with and we’ll email you a reset link. Our setup is similar to that of [11], adding to it two techniques with computational flavor.

The procedure will stop after finitely many steps since all terms in y t of order greater or equal to the conductor c of the semigroup of values of the branch are elim- e inable.

The second technique is the algorithm of Complete Transversal due to J.
