In this logically independent chapter, we present various generalizations of the Borel-Dwork criterion; all of them are derived from a single “main criterion” whose proof relies on the diophantine method already used in the last chapter, namely Gel’fond’s method at several places.

Fuchsian Differential Systems: Arithmetic TheoryWe record here all the properties of p-adic analytic functions (and prove some of them) which will be used in the sequel of the book. We refer the reader to the general introduction [41], or to the more advanced booklet [26]. Everything becomes simpler if one restricts oneself, as we shall do, to the case of disks.

He defined G-functions to be the formal power series y = Σa.x. whose coefficients a lie in some algebraic number field K , which fulfill the following three conditions:

Between the sound and the simple-mindedlist). In this chapter we present a definition of G-functions (inspired by Bombieri “l(fā)ocal-to-global” setting [7]), and define two basic related invariants, namely the size Σ (which coincides with Bombieri’s one, ibid.) and the global radius. We then turn to examples: rational functions, diagonals,

Now we shall start from . “injective” solution (see below for the meaning of “injective”) and shall deduce information about the differential system. To this aim, we follow and simplify an idea of Chudnovsky [18] (and correct a slight mistake in loc. cit. 8.3), in
