The Formal Development

The project described in the linked paper has been incorporated into the Lean mathlib repository. The current state of the p-adic number development can be found in the directory /data/padics/. See also the pull requests here and here.

Since mathlib is regularly updated, we preserve a branch here that shows its state when this paper was written.
