A rigid, irreducible Fuchsian linear q-difference equation can be reduced to a 1st order equation by integral transformations Sakai, Hidetaka


We construct a q-analog of middle convolution. We can reduce the rank of the system by using this, when the system is irreducible, Fuchsian, and of rigidity index 2. In the terms of the middle convolution, we can consider a classification theory of Fuchsian q-difference equations.
