On some multiplicity and mixed multiplicity formulas (Forum Math. 26(2014), 413-442)
摘要:
本文给出了多分次模$M$的混合重数和任意理想的混合重数的可加性和约化公式,并建立了$M.$的所有混合重数之和的递推公式。作为这些公式的应用,我们得到了多分次Rees模的重数的递推公式。
英文摘要:
This paper gives the additivity and reduction formulas for mixed multiplicities of multi-graded modules $M$ and mixed multiplicities of arbitrary ideals, and establishes the recursion formulas for the sum of all the mixed multiplicities of $M.$ As an application of these formulas we get the recursion formulas for the multiplicity of multi-graded Rees modules.
