摘要

我们计算了非阿基米德域上 Berkovich 射影直线中第 nn 层 Trucco 树 Γn\Gamma_nn0n\ge 0)上度数 >1>1 的多项式 PP 的迭代 PjP^jj1j\ge 1)的结式测度,并确定了它们的重心。作为应用,我们研究了当 nn\to\infty 时这些重心的渐近行为,并建立了 PjP^j 的 Rumely 极小结式轨迹的均匀平稳性,或等价地,当 jj\to\inftyPjP^j 的势半稳定约化轨迹的均匀平稳性。我们还建立了结式测度本身在 nn\to\infty 时的若干等分布结果。

37 pages, 1 figure. The terminologies are made more informative and the title is slightly modified. The presentation is improved, and the Hilbert-Mumford GIT is dispensed with in all the proofs but for in reformulating the identity (1.1) as Theorem 4
