Abstract: this paper will work for any of the different formulations of Martin-Lof's type theory. 2 The construction of the interpretation (Update)

Context of citations to this paper:   More

.... presents a proof irrelevant model of Martin Lof s theory of types with explicit substitution; that is, a model in the style of [Smi88], in which types are interpreted as truth values and objects (or proofs) are irrelevant. The fundamental difference here is the need to cope...

...of defining families of sets by structural recursion. For example, the predicate Z (as used in the type theoretic proof that 0 6= s(n) [29, 43]) with the recursion equations Z(0) Z(s(n) is defined in terms of universes and the rule of N elimination. Martin Lof [27]...
