Consider the following restriction of the polymorphically typed lambda calculus ("System F"). All quantifications are parameter free. In other words, in every universal ...
We show that unary PCF, a very small fragment of Plotkin’s PCF [?], cidable observational pre-order, and that its fully abstract model is effectively presentable. This is in ma...
Interesting properties of programs can be expressed using contextual equivalence. The latter is difficult to prove directly, hence (pre-)logical relations are often used as a tool ...
Abstract. Earlier we introduced Constraint Lambda Calculi which integrate constraint solving with functional programming for the simple case where the constraint solver produces no...
This paper presents an untyped lambda calculus, extended with object primitives that reflect the capabilities of so-called delegation-based object-oriented languages. A type infer...
