Abstract

In this paper, we establish, under convenient diophantine assumptions, a complete analytic classification of qq-difference modules over the field of germs of meromorphic functions at zero, proving some analytic analogs of the results by Soibelman and Vologodsky, cf. math.AG/0205117, and by Baranovsky and Ginzburg, cf. alg-geom/9607008.
