The space of monodromy data for the Jimbo-Sakai family of -difference equations
Yousuke Ohyama, Jean-Pierre Ramis, Jacques Sauloy
We formulate a geometric Riemann-Hilbert correspondence that applies to the derivation by Jimbo and Sakai of equation -PVI from ``isomonodromy'' conditions. This is a step withi…

The q-analogue of the wild fundamental group (II)
J. -P. Ramis, J. Sauloy
In [RS1], we defined q-analogues of alien derivations and stated their basic properties. In this paper, we prove the density theorem and the freeness theorem announced in loc. cit.…

The q-analogue of the wild fundamental group (I)
J. -P. Ramis, J. Sauloy
We describe an explicit construction of galoisian Stokes operators for irregular linear q-difference equations. These operators are parameterized by the points of an elliptic curve…
