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...
The last few years have seen the development of statically typed object based (also called prototype-based) programming languages. Two proposals, namely the Lambda Calculus of Obje...
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. In 1994 Herbelin started and partially achieved the programme of showing that, for intuitionistic implicational logic, there is a Curry-Howard interpretation of sequent c...
