Abstract

A finite set {F1, ...,Fn} of terms of λ-calculus is said to be:
  • separable iff, given n arbitrary terms X1, ..., Xn, there exists a context C [ ] such that C[Fi]=Xi for 1≤i≤n

  • semi-separable iff, given n−1 arbitrary terms X1, ..., Xn−1 there exists a context C [ ] such that C [Fi]=Xi for 1≤i ≤n−1 and C [Fn] is unsolvable.

In the present paper the constructive characterization of (semi)-se parability of finite sets of terms is given inside Scott's D-models of the λ-calculus.
