Filter-regular sequences and mixed multiplicities
arXiv:0901.3825
Abstract
Let be a finitely generated standard multigraded algebra over an Artinian local ring ; a finitely generated multigraded -module. This paper answers to the question when mixed multiplicities of are positive and characterizes them in terms of lengths of -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).
