对于多项式环R上的一个n阶生成分次模M,存在一个与线性滤子正则序列相关联的生成元系,称为Weierstrass基。在本文中,我们首先描述了Weierstrass基的性质,并考虑了它们与一般Gröbner基的关系,然后给出了它们存在的一个新的证明,其中M是R上分次自由模的齐次子模.
For a finitely generated graded module M over a polynomial ring R, there is a special system of its generators associated with a linear filter-regular sequence, which is called a Weierstrass basis. In this paper, we describe first properties of Weierstrass bases keeping in mind their relations with generic Gröbner bases and then give a new proof for their existence, in the case where M is a homogeneous submodule of graded free module over R.
