Abstract.
Let S be a finitely generated standard multigraded algebra over an Artinian local ring A, and let M be a finitely generated multigraded S-module. This paper answers the question when mixed multiplicities of M are positive and characterizes them in terms of lengths of A-modules. As an application, we get interesting results on mixed multiplicities of ideals, and recover some early results.
