چکیده
We consider the notion of mixed multiplicities for multigraded modules by using Hilbert series, and this is later applied to study projective degrees rational maps . use a general framework determine map via computation multiplicity saturated special fiber ring. As specific applications, we provide explicit formulas all determined perfect ideals height two or Gorenstein three.

Computing Dynamical Degrees of Rational Maps on Moduli Space
The dynamical degrees of a rational map f : X 99K X are fundamental invariants describing the rate of growth of the action of iterates of f on the cohomology of X. When f has nonempty indeterminacy set, these quantities can be very difficult to determine. We study rational maps f : XN 99K XN , where XN is isomorphic to the Deligne-Mumford compactificationM0,N+3. We exploit the stratified struct...
متن کاملTypical Dynamics of Plane Rational Maps with Equal Degrees
Let f : CP 99K CP be a rational map with algebraic and topological degrees both equal to d ≥ 2. Little is known in general about the ergodic properties of such maps. We show here, however, that for an open set of automorphisms T : CP → CP, the perturbed map T ◦f admits exactly two ergodic measures of maximal entropy log d, one of saddle and one of repelling type. Neither measure is supported in...
متن کاملPositivity of Mixed Multiplicities
Let R = ⊕(u,v)∈N2R(u,v) be a standard bigraded algebra over an artinian local ring K = R(0,0). Standard means R is generated over K by a finite number of elements of degree (1, 0) and (0, 1). Since the length l(R(u,v)) of R(u,v) is finite, we can consider l(R(u,v)) as a function in two variables u and v. This function was first studied by van der Waerden [W] and Bhattacharya [B] who proved that...

We investigate the rational homotopy classification problem for the components of some function spaces with Sn or cPn as target space.
متن کاملFilter-regular Sequences and Mixed Multiplicities
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 interesting results on mixed multiplicities of ideals, and recover some early results in [Te] and [TV].
