Abstract
In this article we show that all periods of uniformizable -modules (resp. their coordinates) can be obtained via specializing a rigid analytic trivialization of a related dual -motive at . The proof is even constructive. The central object in the construction is a subset of the Tate algebra points of which turns out to be isomorphic to the period lattice of via kind of generating series in one direction and residues in the other. This isomorphism even holds for arbitrary -modules , even non-abelian ones.
