TLDR
However, Scott does realize that the approach argued for above is simply an argument for an approach that accomodates human understanding of computation and that the operational approach must not be ignored because the machines that the programs of study run on are not capable of dealing with such an abstract level of understanding.
Abstract
However, Scott does realize that the approach argued for above is simply an argument for an approach that accomodates human understanding of computation and that the operational approach must not be ignored because, as he points out, the machines that the programs of study run on are not capable of dealing with such an abstract level of understanding. That is, the computaional approach should not be abandoned because the machines that we build operate on that lower level.

Classifying topoi in synthetic guarded domain theory

TL;DR: It is shown that several important topos models of SGDT classify very simple geometric theories, and that the passage to various forms of multi-clock guarded recursion can be rephrased more compositionally in terms of the lower bagtopos construction of Vickers and variations thereon due to Johnstone.

An abstract strong normalization theorem

TL;DR: A strong normalization theorem for abstract term rewriting systems based on domain-theoretic models is proved and extensions of Godel's system T by various forms of recursion related to bar recursion are extended.

Towards a Higher-Order Mathematical Operational Semantics

TL;DR: A theory of abstract GSOS specifications for higher-order languages is developed, in effect transferring the core principles of Turi and Plotkin’s framework to a higher- order setting, and a general compositionality result is given that applies to all systems speci fied.

An Order Model for Infinite Classical States

TL;DR: In this paper, the authors extended the Coecke and Martin model to a model for the infinite classical states, which are the states which result when an observable is applied to a quantum system.

On the lambda calculus with constructors

Barbara Petit
TL;DR: A polymorphic type system for this calculus is proposed, and a realisability model is developed, based on Girard's reducibility candidates, which leads to a strong normalisation result for the typed calculus, and guaranties that the type system prevents match failure.
