滤波器-正则序列和混合多重性
Filter-regular sequences and mixed multiplicities
摘要:
设$S$是Artinian局部环$A$上的一个标准生成的多重分次代数,$M$是一个标准生成的多重分次$S$ -模.本文回答了$M$的混合重数为正的问题,并用$A$ -模的长度刻画了它们.作为应用,我们得到了理想的混合重数的结果(命题4.4和定理4.5),并恢复了Risler和Teissier [Te](见注4.8),Trung和Verma [TV](见注4.6)的结果.
英文摘要:
Let $S$ be a finitely generated standard multigraded algebra over an Artinian local ring $A$; $M$ a finitely generated multigraded $S$-module. This paper answers to the question when mixed multiplicities of $M$ are positive and characterizes them in terms of lengths of $A$-modules. As an application, we get results on mixed multiplicities of ideals (Proposition 4.4 and Theorem 4.5), and recover the results of Risler and Teissier [Te](see Remark 4.8), Trung and Verma [TV](see Remark 4.6).
