Abstract

Starting from an executable "shared axiomatization" of a number of bi-interpretable theories (Peano arithmetic, hereditarily finite sets and functions) we introduce generic algorithms that can be instantiated to implement the usual arithmetic operations in terms of (purely symbolic) hereditarily finite constructs, as well as the type language of Gödel's System T. The Haskell code in the paper is available at http://logic.cse.unt.edu/tarau/research/2010/short_shared.hs.
