Abstract or Description

Singleton kinds provide an elegant device for expressing type equality information resulting from modern module languages, but they can complicate the metatheory of languages in which they appear. I present a translation from a language with singleton kinds to one without, and prove this translation to be sound and complete. This translation is useful for type-preserving compilers generating typed target languages. The proof of soundness and completeness is done by normalizing type equivalence derivations using Stone and Harper's type equivalence decision procedure.
