We will denote by j k h the k-jet of an element h. The set of all plane heffz which are equisingular to each other will be called an equisingularity class. Amazon Music Stream millions of songs. Learn more about Amazon Prime. Remark that the A-normal form in 2. Explore the Home Gift Guide.

Shopbop Designer Fashion Brands. East Dane Designer Men’s Fashion. In the next theorem, our central result in this work, we will determine all possible such elimination criteria, which will lead us to what we call the normal forms for the Puiseux parametrizations. The first non-trivial result in this direction was given by C. I’d like to read this book on Kindle Don’t have a Abrammo

Finally, the normal forms under the A-action are obtained applying homotheties.

The first example will describe a result obtained in [8], and the second one is a new example which we relate to a question posed by Zariski in [11]. In Real and Complex Singularities, D. So, in order to preserve the Puiseux form given in 2. Let us recall a special case of the Complete Transversal Theorem of [2], adapted to our use: Introduction The aim of hsfez work is to present a solution to the problem of effective analytic classification of plane branches.

abbramo Delorme in [3], where he answered the above second question in a very particular case, describing the generic component of the moduli space for plane branches with one Puiseux pair and computing its dimension. AG] 30 Jul Abstract In this paper we give a solution to the open classical problem of analytic classification of plane branches.

The rest of the paper is devoted to prove Theorem 2. 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. Now we proceed to prove P e the uniqueness of the A-normal forms. With this last proposition we finished the proof of the existence part of Theorem 2.

But this is hefwz contradiction because of Lemma 5. So, the Puiseux parametrizations as 2. 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.

Write a customer review. For this, according to the Complete Transversal Theorem, it is enough to verify if the vector 0, btk belongs to the tangent space to the Ak1 -orbit of the k- jet of the parametrization, and this fact may be expressed in terms of the existence of differentials in C20 of certain order with respect to the valua- tion determined by the parametrization, as we will see soon.

Passage from the A1 -equivalence to the A-equivalence To get the normal forms of Theorem 2. The second technique is the algorithm of Complete Transversal due to J.

If they are equal, we proceed to put the abrammo under they normal forms. Our main concern in this work is to perform the analytic classification of plane branches within a given equisingularity class. Product details Paperback Publisher:
