Dialectica Interpretation of Intuitionistic Logic
The interpretation has two components: a formula translation and a proof translation. The formula translation describes how each formula of Heyting arithmetic is mapped to a quantifier-free formula of the system T, where and are tuples of fresh variables (not appearing free in ). Intuitively, is interpreted as . The proof translation shows how a proof of has enough information to witness the interpretation of, i.e. the proof of can be converted into a closed term and a proof of in the system T.

Famous quotes containing the word logic:
“...some sort of false logic has crept into our schools, for the people whom I have seen doing housework or cooking know nothing of botany or chemistry, and the people who know botany and chemistry do not cook or sweep. The conclusion seems to be, if one knows chemistry she must not cook or do housework.”
—Ellen Henrietta Swallow Richards (1842–1911)
