Query: Algebraic construction of the Stokes sheaf for irregular linear
  q-difference equations   The local analytic classification of irregular linear q-difference equations
has recently been obtained by J.-P. Ramis, J. Sauloy and C. Zhang. Their
description involves a q-analog of the Stokes sheaf and theorems of
Malgrange-Sibuya type and is based on a discrete summation process due to C.
Zhang. We show here another road to some of these results by algebraic means
and we describe the q-Gevrey devissage of the q-Stokes sheaf by holomorphic
vector bundles over an elliptic curve.
