Although Glivenko-type theorems have been shown for substructural propositional and first-order logics (see Ferreira-Ono and Galatos-Ono ), no such result is known for higher-order logic (as to the first-order case, is typed and categorical while is single-sorted and proof-theoretical). ILT was proposed by G. Plotkin and also independently by P. Wadler. Applications: We apply the correspondences to prove a result about logic, and a result about . Keywords: Categorical logic, categories with families, constructive type theory, dependent types, internal type theory, proof assistants. The justification of this terminology is that it can be shown, only using the rules of type theory, that any such type can indeed be seen as a groupoid in the usual categorical sense, where the objects are the elements of this type, the set of morphisms between \(a\) and \(b\) being represented by the set \(\mathbf{Id}_A (a,b)\).
