Semantics for a Quantum Programming Language by Operator Algebras [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2014
This paper presents a novel semantics for a quantum programming language by operator algebras, which are known to give a formulation for quantum theory that is alternative to the one by Hilbert spaces.

Unifying Theories of Mobile Channels [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2016
In this paper we present the denotational semantics for channel mobility in the Unifying Theories of Programming (UTP) semantics framework. The basis for the model is the UTP theory of reactive processes (precisely, the UTP semantics for Communicating ...

Inductive Definition and Domain Theoretic Properties of Fully Abstract [PDF]

open access: yes, 2007
A construction of fully abstract typed models for PCF and PCF^+ (i.e., PCF + "parallel conditional function"), respectively, is presented. It is based on general notions of sequential computational strategies and wittingly consistent non-deterministic ...

An Effect System for Algebraic Effects and Handlers [PDF]

open access: yesLogical Methods in Computer Science, 2014
We present an effect system for core Eff, a simplified variant of Eff, which is an ML-style programming language with first-class algebraic effects and handlers. We define an expressive effect system and prove safety of operational semantics with respect

Extensional and Intensional Semantics of Bounded and Unbounded Nondeterminism [PDF]

open access: yesLogical Methods in Computer Science, 2021
We give extensional and intensional characterizations of functional programs with nondeterminism: as structure preserving functions between biorders, and as nondeterministic sequential algorithms on ordered concrete data structures which compute them.

Quantum Turing automata [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2014
A denotational semantics of quantum Turing machines having a quantum control is defined in the dagger compact closed category of finite dimensional Hilbert spaces.

Mechanized semantics [PDF]

open access: yes, 2010
The goal of this lecture is to show how modern theorem provers---in this case, the Coq proof assistant---can be used to mechanize the specification of programming languages and their semantics, and to reason over individual programs and over generic ...

Semantics of a Typed Algebraic Lambda-Calculus [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2010
Algebraic lambda-calculi have been studied in various ways, but their semantics remain mostly untouched. In this paper we propose a semantic analysis of a general simply-typed lambda-calculus endowed with a structure of vector space.

A Provenance Tracking Model for Data Updates [PDF]

open access: yes, 2012
For data-centric systems, provenance tracking is particularly important when the system is open and decentralised, such as the Web of Linked Data. In this paper, a concise but expressive calculus which models data updates is presented.

Reversible Barbed Congruence on Configuration Structures [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2015
A standard contextual equivalence for process algebras is strong barbed congruence. Configuration structures are a denotational semantics for processes in which one can define equivalences that are more discriminating, i.e.
