The word semantics has Greek roots1 and was first used in linguistics. Here, one distinguishes among syntax, the study of the structure of lan- guages, semantics, the study of meaning, and pragmatics, the study of the use of language. In computer science we make a similar distinction between syntax and se- mantics. The languages that we are interested in are programming languages in a very general sense. The ‘meaning’ of a program is its behaviour, and for this reason programming language semantics is the part of programming language theory devoted to the study of program behaviour. Programming language semantics is concerned only with purely internal aspects of program behaviour, namely what happens within a running pro- gram. Program semantics does not claim to be able to address other aspects of program behaviour – e.g.

DSIE is a series of meetings that started in the first edition of ProDEI, in the scholar year 2005/06; its main goal has always been to provide a forum for discussion on, and demonstration of, the practical application of a variety of scientific and technological research issues, particularly in the context of information technology, computer science and computer engineering. DSIE Symposium comes out as a natural conclusion of a mandatory ProDEI course called "Methodologies for Scientific Research" (MSR), this year also available to MAP-tel students, leading to a formal assessment of the PhD students first year’s learned competencies on those methodologies.

  • From Theory to Practice of Algebraic Effects and Handlers
    Report from Dagstuhl Seminar 16112 From Theory to Practice of Algebraic Effects and Handlers Edited by Andrej Bauer1, Martin Hofmann2, Matija Pretnar3, and Jeremy Yallop4 1 University of Ljubljana, SI, [email protected] 2 LMU München, DE, [email protected] 3 University of Ljubljana, SI, [email protected] 4 University of Cambridge, GB, [email protected] Abstract Dagstuhl Seminar 16112 was devoted to research in algebraic effects and handlers, a chapter in the principles of programming languages which addresses computational effects (such as I/O, state, exceptions, nondeterminism, and many others). The speakers and the working groups covered a range of topics, including comparisons between various control mechanisms (handlers vs. delimited control), implementation of an effect system for OCaml, compilation techniques for algebraic effects and handlers, and implementations of effects in Haskell.

  • Free-Algebra Models for the Π-Calculus
    CORE Metadata, citation and similar papers at core.ac.uk Provided by Elsevier - Publisher Connector Theoretical Computer Science 390 (2008) 248–270 www.elsevier.com/locate/tcs Free-algebra models for the π-calculus Ian Stark Laboratory for Foundations of Computer Science, School of Informatics, The University of Edinburgh, Scotland, United Kingdom Abstract The finite π-calculus has an explicit set-theoretic functor-category model that is known to be fully abstract for strong late bisimulation congruence. We characterize this as the initial free algebra for an appropriate set of operations and equations in the enriched Lawvere theories of Plotkin and Power. Thus we obtain a novel algebraic description for models of the π-calculus, and validate an existing construction as the universal such model. The algebraic operations are intuitive, covering name creation, communication of names over channels, and nondeterministic choice; the equations then combine these features in a modular fashion. We work in an enriched setting, over a “possible worlds” category of sets indexed by available names. This expands significantly on the classical notion of algebraic theories: we can specify operations that act only on fresh names, or have arities that vary as processes evolve. Based on our algebraic theory of π we describe a category of models for the π-calculus, and show that they all preserve bisimulation congruence. We develop a direct construction of free models in this category; and generalise previous results to prove that all free-algebra models are fully abstract. We show how local modifications to the theory can give alternative models for πI and the early π-calculus.

Interest in such threads has increased recently with the introduction of Automatic Mutual Exclusion (AME) and the problem of programming multicore systems. Martín Abadi, Gordon Plotkin A Model of Cooperative Threads Introduction A Language for Cooperative Threads An Elementary Fully Abstract Denotational Semantics An Algebraic View of the Semantics Conclusions What we do We describe a simple language for cooperative threads and give it a mathematically elementary fully abstract (may) semantics of sets of traces, being transition sequences of, roughly, the form: 0 0 u = (σ1; σ1) ::: (σm; σm) à la Abrahamson, the authors, Brookes etc, but adapted to incorporate thread spawning. Following the algebraic theory of effects, we characterise the semantics using a suitable inequational theory, thereby relating it to standard domain-theoretic notions of resumptions.

    Symposium for Gordon Plotkin Edinburgh 07-08/09/2006 From Partial Lambda-calculus to Monads Eugenio Moggi [email protected] DISI, Univ. of Genova GDP symposium – p.1/11 AIM: recall influence of Plotkin (and others) on my PhD research (and beyond) Mainly overview of published work + personal comments and opinions Please interrupt to correct my account or to add your comments Main focus on Partial lambda-calculus [Mog88] 1984-1988 but work placed in broader context: partiality in: Logic, Algebra, Computability lambda-calculi as: PL [Lan66, Plo75], ML [Sco93, GMW79, Plo85] domain theory [FJM+96]: classical, axiomatic, synthetic Applications of monads [Mac71, Man76] for computational types (lifting and recursion) [Mog89, Mog91] 1988-. in pure functional languages (Haskell) – Wadler et al. for collection types (in databases) – Buneman et al. including recent contributions by Plotkin et al. [HPP02] GDP symposium – p.2/11 1984 reformulation of domain theory using partial continuous maps [Plo85] Previous relevant work (. -1983) 1982 more systematic study of categories of partial maps [Obt86, CO87] partiality in algebraic specifications: [Bur82] partiality in (intuitionistic) logic: LPE [Fou77, Sco79], LPT [Bee85] mismatch between lambda-calculus and programming languages [Plo75] λV CBV axioms (λx.t)v > t[x: =v] and (λx.vx) > v with v: : = x j λx.t values λp is derived from models like λV is derived from operational semantics λV ⊂ λc ⊂ λp are correct (but incomplete) for CBV (on untyped λ-terms) λc on (simply typed) λ-terms is inverse image of
