A classical higher-order logic PFsub of partial functions is defined. The logic extends a version of Farmer's logic PF by enriching the type system of the logic with subset ty...
We study, from a classical point of view, how the truth of a statement about higher type functionals depends on the underlying model. The models considered are the classical set-t...
