Abstract: | Ap-adic subanalytic set shares with a real subanalytic set the fundamental property that its singular locus is itself subanalytic. Furthermore, given ap-adic subanalytic function ? with domain contained in ? p m , there is an integerL such that for any pointx 0 ∈ ? p m in a neighborhood of whichf is defined,f has a Taylor approximation up to orderL atx 0 if, and only if, ? is analytic aroundx 0. These results extend to thep-adic fields real variables theorems by M. Tamm [21]. |
