Abstract
In the Workshop the central theme is a conjecture, see (4.2). On this conjecture work has
been done from various directions: mixed characteristic, G-functions, equidistribution, Galoisorbits.
Special cases have been proved (Andr´e, Moonen, Edixhoven, Clozel, Ullmo, Zhang,
Yafaev, and several others); the general case seems to be open.
