p-adic

From p +‎ -adic. The letter p follows common number theory usage in representing an arbitrary prime number; the suffix -adic signals that properties of the number p (generally, those due to its being prime, and specifically those of a specified p) are fundamental to the theory and determine the properties of the resulting construction.

1. (number theory) Of, pertaining to, (ultimately) derived from or defined in the context of p-adic numbers.
   • 1995, Alain Escassut, Analytic Elements in P-adic Analysis, World Scientific, page v:

     The theory of p-adic analytic functions in domains other than simple disks is not very well known yet, although such kind of functions happens to intervene in questions linked to p-adic functional analysis, number theory, and others.

     Definition 3.3.3 The ring of p-adic integers is the valuation ring

     ${\displaystyle \mathbb {Z} _{p}=\{x\in \mathbb {Q} _{p}:|x|_{p}\leq 1\}}$.

     The paper is organized as follows:

     2. Preliminaries

     3. A p-adic Cauchy problem

     4. The p-adic Hilbert transform

     5. The boundaries in the p-adic space ${\displaystyle L^{q}}$

The synonym ℓ-adic is used in some contexts: for instance, in regard to Galois representations (G-modules, where the Galois group G is a vector space over the field of ℓ-adic numbers), and in algebraic geometry, where ℓ-adic cohomology is one of the "classical" constructions of Weil cohomologies.
