Puiseux power series solutions for systems of equations

Fuensanta Aroca, Giovanna Ilardi, Lucia Lopez de Medrano

摘要:

本文给出了一种算法,用于计算代数方程的零点在奇点处的局部参数化所引起的级数的逐项多元Puixix级数展开式。该算法是牛顿法在平面代数曲线上的推广,用系统生成的理想的热带簇代替牛顿多边形。作为推论,我们推出的性质的热带品种的准普通奇点。

英文摘要:

We give an algorithm to compute term by term multivariate Puiseux series expansions of series arising as local parametrizations of zeroes of systems of algebraic equations at singular points. The algorithm is an extension of Newton's method for plane algebraic curves replacing the Newton polygon by the tropical variety of the ideal generated by the system. As a corollary we deduce a property of tropical varieties of quasi-ordinary singularities.
