摘要翻译:
本文的第二部分将第一部分描述的下降理论加强到有理映射、任意基场和由对应给出的动力学。特别地,我们得到了将任何差场扩张分解为有限的、域内的和基于一的差场扩张的塔。为了得到第一部分的“动力Northcott”定理1.11的尖锐形式,这是必需的。

英文摘要:
This second part of the paper strengthens the descent theory described in the first part to rational maps, arbitrary base fields, and dynamics given by correspondences. We obtain in particular a decomposition of any difference field extension into a tower of finite, field-internal and one-based difference field extensions. This is needed in order to obtain the "dynamical Northcott" Theorem 1.11 of Part I in sharp form.
