Abstract

We show that any λ-model gives rise to a λµ-model, in the sense that if we have M =λµ N in the equational theory of type free λµ-calculus then [[M]] = D [[N]] holds true for some structure 〈[[-]], D〉 induced from a λ-model. The construction of λµ-models can be given by the use of a fixed point operator and the Gödel-Gentzen translation.
