In particular, strong normalization and λ-definability are investigated. A translation is introduced from intersection typing derivations to Curry typeable terms; the main feature of the proposed technique is that the translation is preserved by β-reduction. This allows to simulate a computation starting from a term typeable in the intersection discipline by means of a computation starting from a simply typeable term. Our approach naturally leads to prove strong normalization in the intersection system by means of purely syntactical techniques. In addition, the presented method enables us to give a proof of a conjecture proposed by Leivant in 1990, namely that all functions uniformly definable using intersection types are already definable using Curry types. %K lambda calculusCurry types %K intersection types %K lambda-definability %K lambda-terms %K strong normalization %R 10.1109/LICS.1999.782598 %U http://mclab.di.uniroma1.it/publications/papers/papers/Bucciarelli1999.pdf %U https://doi.org/10.1109/LICS.1999.782598 %P 109-118
