Local analytic classification of -difference equations with
arXiv:0802.4223
Abstract
In this paper, we establish, under convenient diophantine assumptions, a complete analytic classification of -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.
