Uniform rationality of the Poincaré series of definable, analytique equivalence relations on local fields

Submission date: 27 October 2016


Poincaré series of p-adic, definable equivalence relations have been studied in various cases since Igusa's and Denef's work related to counting solutions of polynomial equations modulo a power of prime p. General semi-algebraic equivalence relations on local fields have been studied uniformly in p recently, we generalize the rationality result to the analytic case, unifomly in p. In particular, the results hold for large positive characteristic local fields. We also introduce rational motivic constructible functions and their motivic integrals, as a tool to prove our main results.
