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.

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 ...

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.

METRIC DENOTATIONAL SEMANTICS FOR REMOTE PROCESS DESTRUCTION AND CLONING

open access: yesStudia Universitatis Babes-Bolyai: Series Informatica, 2017
We present a denotational semantics designed with continuations for a concurrent language providing a mechanism for synchronous communication, together with constructions for process creation, remote process destruction and cloning.

QWIRE Practice: Formal Verification of Quantum Circuits in Coq [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2018
We describe an embedding of the QWIRE quantum circuit language in the Coq proof assistant. This allows programmers to write quantum circuits using high-level abstractions and to prove properties of those circuits using Coq's theorem proving features. The

Denotational Semantics and Refinement [PDF]

open access: yesElectronic Workshops in Computing, 1997
Denotational descriptions are frequently presented in terms of a sequence of descriptions of programming languages of increasing complexity. We discuss a formal approach to the study of such description sequences in terms of a refinement relation, showing how the informal use made of this approach in tutorial introductions to denotational semantics may

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.

Analyzing logic programs with dynamic scheduling [PDF]

open access: yes, 1994
Traditional logic programming languages, such as Prolog, use a fixed left-to-right atom scheduling rule. Recent logic programming languages, however, usually provide more flexible scheduling in which computation generally proceeds leftto- right but in ...

Semantics, Specification Logic, and Hoare Logic of Exact Real Computation [PDF]

open access: yesLogical Methods in Computer Science
We propose a simple imperative programming language, ERC, that features arbitrary real numbers as primitive data type, exactly. Equipped with a denotational semantics, ERC provides a formal programming language-theoretic foundation to the algorithmic ...
