The aim of our work is to provide an infrastructure for formal proofs over Generic Haskell-style polytypic programs. For this goal to succeed, we must have a definition of polytypic programming which is both fully formal and as close as possible to the definition in Generic Haskell. In this paper we show a formalization in the proof assistant Coq of type and term specialization. Our definition of term specialization can be interpreted as a formal proof that the result of term specialization has the type computed by type specialization.
