Sequentiality in an Extensional Framework

We present a cartesian closed category of dI-domains with coherence and strongly stable functions which provides a new model of PCF, where terms are interpreted by functions and where, at rst order, all functions are sequential. We show how this model can be reened in such a way that the theory it induces on the terms of PCF be strictly ner than the theory induced by the Scott model of continuo...

An Extensional Böhm Model

We show the existence of an infinitary confluent and normalising extension of the finite extensional lambda calculus with beta and eta. Besides infinite beta reductions also infinite eta reductions are possible in this extension, and terms without head normal form can be reduced to bottom. As corollaries we obtain a simple, syntax based construction of an extensional Böhm model of the finite la...

Extensional Normalization in the Logical Framework with Proof Irrelevant Equality

We extend the Logical Framework by proof irrelevant equality types and present an algorithm that computes unique long normal forms. The algorithm is inspired by normalization-by-evaluation. Equality proofs which are not reflexivity are erased to a single object ∗. The algorithm decides judgmental equality, its completeness is established by a PER model.

Observable Sequentiality and Full Abstraction 1 Full Abstraction and Sequentiality

One of the major challenges in denotational semantics is the construction of fully abstract models for sequential programming languages. For the past fteen years, research on this problem has focused on developing models for PCF, an idealized functional programming language based on the typed lambda calculus. Unlike most practical languages, PCF has no facilities for observing and exploiting th...

Sequentiality in Bounded Biorders

We study a notion of bounded stable biorder, showing that the monotone and stable functions on such biorders are sequential. We construct bounded biorder models of a range of sequential, higher-order functional calculi, including unary PCF, (typed and untyped) call-by-value and lazy λ-calculi, and non-deterministic SPCF. We prove universality and full abstraction results for these models by red...
