In the first part of the paper we give a definition of G_q-function and weestablish a regularity result, obtained as a combination of a q-analogue of theAndre'-Chudnovsky Theorem [And89, VI] and Katz Theorem [Kat70, \S 13].  In the second part of the paper, we combine it with some formal q-analogousFourier transformations, obtaining a statement on the irrationality of specialvalues of the formal $q$-Borel transformation of a G_q-function.

Arithmetic theory of q-difference equations (G_q-functions and q-difference modules of type G, global q-Gevrey series)
