关于由一阶微分系统II定义的亚纯函数

On meromorphic functions defined by a differential system of order 1, II

Tristan Torrelli

摘要:

给定(C ^n,0)上全纯函数的一个非零芽h,研究了理想Ann\_D 1/h由1阶算子生成的条件.当h定义了一个具有孤立奇点的超曲面的一般排列时,我们证明了它是可验证的当且仅当h是加权齐次的,并且-1是它的Bernstein-Sato多项式的唯一整根.当h是乘积时,我们给出一个过程来检验最后一个条件。最后,我们研究了其他一些相关的条件。

英文摘要:

Given a nonzero germ h of holomorphic function on (C^n,0), we study the condition: ``the ideal Ann\_D 1/h is generated by operators of order 1''. When h defines a generic arrangement of hypersurfaces with an isolated singularity, we show that it is verified if and only if h is weighted homogeneous and -1 is the only integral root of its Bernstein-Sato polynomial. When h is a product, we give a process to test this last condition. Finally, we study some other related conditions.
