局部zeta函数的代数估计、稳定性和分布函数的一致估计

Algebraic estimates, stability of local zeta functions, and uniform estimates for distribution functions

D. H. Phong, Jacob Sturm

摘要:

本文发展了一种"代数估计“方法,并用于研究\int_B型积分的稳定性|f(z)|^{- \d }dV,在函数f的小变形下。该估计被描述为函数空间的分层\{R(z)=| P(z)|^{ \e }/|Q(z)|^{ \d }\}通过代数簇,在每个代数簇上,R(z)的积分的大小由显式代数式给出。该方法给出了一个关于Tian在二维空间稳定性的结果的独立证明,并将该结果部分推广到三维空间。在任意维上,结合Siu的一个关键引理,建立了映射c \ra \int_B的连续性|f(z,c)|当f(z,c)是(z,c)的一个全纯函数时,可以得到^{- \d }dV_1 \cdots dV_n.特别是导极点在f中是不连续的,这也加强了Lichtin的一个较早的结果。

英文摘要:

A method of ``algebraic estimates'' is developed, and used to study the stability properties of integrals of the form \int_B|f(z)|^{-\d}dV, under small deformations of the function f. The estimates are described in terms of a stratification of the space of functions \{R(z)=|P(z)|^{\e}/|Q(z)|^{\d}\} by algebraic varieties, on each of which the size of the integral of R(z) is given by an explicit algebraic expression. The method gives an independent proof of a result on stability of Tian in 2 dimensions, as well as a partial extension of this result to 3 dimensions. In arbitrary dimensions, combined with a key lemma of Siu, it establishes the continuity of the mapping c\ra \int_B|f(z,c)|^{-\d}dV_1\cdots dV_n when f(z,c) is a holomorphic function of (z,c). In particular the leading pole is semicontinuous in f, strengthening also an earlier result of Lichtin.
