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.", "revisions": [ { "version": "v1", "updated": "2000-07-01T00:00:00.000Z" } ], "analyses": { "keywords": [ "local zeta functions", "algebraic estimates", "distribution functions", "uniform estimates", "explicit algebraic expression" ], "tags": [ "journal article" ], "publication": { "publisher": "Princeton University and the Institute for Advanced Study", "journal": "Ann.
