A local-global problem for linear differential equations
Marius van der Put, Marc Reversat
An inhomogeneous linear differential equation Ly=f over a global differential field can have a formal solution for each place without having a global solution. The vector space lgl…

Galois theory of q-difference equations
Marius van der Put, Marc Reversat
Choose with 0<|q|<1. The main theme of this paper is the study of linear q-difference equations over the field K of germs of meromorphic functions at 0. It turns…
