TLCA 1999. Intuitionistic logic captures functional programming in a logical way, as can be seen from the Curry-Howard isomorphism between constructive proofs and functional programs. However, there are many structural properties of programs that are not captured within the intuitionistic framework, such as resource usage, computational complexity, and sequentiality. Intuitionistic linear logic can be thought of as a refinement of intuitionistic logic in which the resource consumption properties of functions can be expressed internally. Here, we further refine it to allow the expression of sequencing of computations. We achieve this by controlling the use of the structural rule of exchange to arrive at intuitionistic non-commutative linear logic My earlier post on linguistics reminded me of the Lambek calculus, which is an ordered logic invented in 1958(!) to model how to parse sentences. So I wanted to find a paper on ordered logic (ie, you can't freely swap the order of hypotheses in a context) and link to that.

var wgNotice = ""; var wgNoticeLocal = ""; var wgNoticeLang = "en"; var wgNoticeProject = "wikipedia"; Typed lambda calculus From Wikipedia, the free encyclopedia Jump to: navigation search This article may require cleanup to meet Wikipedia's quality standards Please improve this article if you can. (December 2007) A typed lambda calculus is a typed formalism that uses the lambda-symbol ( ) to denote anonymous function abstraction. Typed lambda calculi are foundational programming languages and are the base of typed functional programming languages such as ML and Haskell and, more indirectly, typed imperative programming languages . They are closely related to intuitionistic logic via the Curry-Howard isomorphism and they can be considered as the internal language of classes of categories , e.g. the simply typed lambda calculus is the language of Cartesian closed categories (CCCs). Traditionally, typed lambda calculi were seen as refinements of the untyped lambda calculus . A more modern view considers typed lambda calculi the more fundamental theory, and untyped lambda calculus a special case with only one type.

The Lambda-calculus, Combinatory Logic, and Type Systems Overview: Three interrelated topics at the heart of logic and computer science. The -Calculus A pure calculus of functional abstraction and function application, with applications throughout logic and computer science. Types The -calculus is good tool for exploring type systems, invaluable both in the foundations of mathematics and for practical programming languages. Pure Type Systems A further generalisation and systematic presentation of the class of type systems found in the -cube. Combinators Combinatory logic shows that bound variables can be eliminated without loss of expressiveness. It has applications both in the foundations of mathematics and in the implementation of functional programming languages. Programming Languages The connections between the lambda-calculus and programming languages are diverse and pervasive. Type systems are an important aspect of programming language design. The -cube A graphical presentation of the relationship between combinatory logic, lambda calculi and related logical systems. The -cube A graphical presentation of the relationship between various typed -calculi, illuminating the structure of Coquand's Calculus of Constructions.

Both the integers and the operations on them are represented as terms in the pure untyped lambda-calculus. The only building blocks are identifiers, abstractions and applications. No constants or delta-rules are used. Reductions follow only the familiar beta-substitution and eta-rules. We also show two approaches of defining a predecessor of a Church numeral. Curiously, none of the arithmetic operations involve the Y combinator; even the division gets by without Y. Addition, multiplication, squaring, and exponentiation are easily expressed in lambda-calculus. We discuss two approaches to their "opposites" subtraction, division, finding of a square root and of a discrete logarithm. The "opposite" operations present quite a challenge. One approach, based on fixpoints, is more elegant but rather impractical. The "dual" approach, which relies on counting, leads to constructive and useful, albeit messy, terms.

9. A Normaliser For Pure And Typed Lambda-calculus This program provides a useful environment to write programs in pure or typed lambdacalculus. Given a term, the program will compute and print its normal http://www.lama.univ-savoie.fr/~raffalli/normaliser.html

A Normaliser for pure and typed lambda-calculus. Version 2.3 Overview This program provides a useful environment to write programs in pure or typed lambda-calculus. Given a term, the program will compute and print its normal form. This means that, unlike most functional languages, computation is done under function abstractions (or lambdas). This software might be used for teaching lambda-calculus or just to play with it. It has some interesting features : Three modes of evaluation: lazy: call-by-name with some sharing left: call-by-name with no sharing trace: call-by-name and printing of each beta-reduction step or tracing of particular functions. It is implemented in Objective Caml (a dialect of ML) so easily portable to many machines, even very small ones. It is quite efficient. It uses a High-Order-Abstract-Syntax representation of terms which help to benefit from ML management of closure. This is specially optimised to give both reasonable performance in speed and memory. It's possible to terminate computation of factorial 100 with a binary encoding of natural numbers ! You can define terms (even using recursive definitions) or include files. This gives enough modularity to write fairly large terms.

". And as in Haskell I'll allow multiple variables between the " " and " "; it's just a shorthand for multiple lambdas. So what about the dependent function type? The syntax suggests (x::t)->u , so I'll use that. And when the variable doesn't occur we'll write t->u as usual. For type variables Haskell (well, not Haskell 98, but extensions) uses forall (a::*) . t , so I'll allow that too. An example, the identity function: with type forall (a::*) . a->a And using it id Int 5 Writing a pretty printer and parser for this is pretty straight forward so I'll skip that and just point you to the code . BTW, instead of using Parsec for the parser like everyone else I used ReadP. The ReadP library is very nice, partly because the alternative operator is actually commutative (unlike Parsec).

As a minimal environment for the study of permutative reductions an extension LambdaJ of the untyped lambda-calculus is considered. In this non-terminating system with non-trivial critical pairs, confluence is established by studying triangle properties that allow to treat permutative reductions modularly and could be extended to more complex term systems with permutations. Standardization is shown by means of an inductive definition of standard reduction that closely follows the inductive term structure and captures the intuitive notion of standardness even for permutative reductions.

Intuitively, this means to reduce a number of redexes (existing in a lambda term) simultaneously. During the talk, after reevaluating the significance of the notion of parallel reduction in Tait-and-Martin-L¶f type proofs of the Church-Rosser theorems, we show that the notion of parallel reduction is also useful in giving short and direct proofs of some other fundamental theorems in reduction theory of lambda calculus.

This paper surveys a part of the theory of beta-reductions in lambda calculus which might aptly be called perpetual reductions. The theory is concerned with perpetual reduction strategies, i.e., reduction strategies that compute infinite reduction paths from lambda terms (when possible), and with perpetual redexes, i.e., redexes whose contraction in lambda terms preserves the possibility (when present) of infinite reduction paths.

Bertoni, Bshm, Miglioli), World Scientific, Mantova 1989, pp. 413-424. Abstract: In this paper it is studied the problem of stating a Curry-Howard isomorphism for Girard's Linear Logic. Two solutions are proposed: one for the intuitionistic variant of the logic and one for a subsytem of the logic which includes the multiplicative and exponential connectives. Different calculi have been developed for the two cases. S. Valentini, The judgement calculus for Intuitionistic Linear Logic: proof theory and semantics, Abstract: In this paper I propose a new set of rules for a judgement calculus, i.e. a typed lambda calculus, based on Intuitionistic Linear Logic; these rules ease the problem of defining a suitable mathematical semantics. A proof of the canonical form theorem for this new system is given: it assures, beside the consistency of the calculus, the termination of the evaluation process of every well-typed element. The definition of the mathematical semantics and a completeness theorem, that turns out to be a representation theorem, follow. This semantics is the basis to obtain a semantics for the evaluation process of every well-typed program. U. Solitro, S. Valentini

27. Major Scientific Accomplishments 2000. Reflexive Lambda-calculus It may be regarded as the pure lambda version of the Logic of Proofs LP (cf. and combinatory logic, typed lambdacalculus and modal lambda-calculus. http://www.cs.gc.cuny.edu/~sartemov/accom.html

Major scientific accomplishments . Reflexive lambda-calculus. The Curry-Howard isomorphism converting intuitionistic proofs into typed lambda-terms is a simple instance of an internalization property of a our system lambda-infinity which unifies intuitionistic propositions (types) with lambda-calculus and which is capable of internalizing its own derivations as lambda-terms. We establish confluence and strong normalization of lambda-infinity. The system lambda-infinity is confluent and strongly normalizable (a joint result with J.Alt) , considerably extends the expressive power of each of its major components: typed lambda-calculus, intuitionistic and modal logic. It may be regarded as the pure lambda version of the Logic of Proofs LP (cf. below). Reflexive lambda-calculus is likely to change our conception of the appropriate syntax and semantics for ambda-calculus based programming languages, systems of automated deduction and formal verification. . An explicit provability model for verification. The traditional (implicit) provability model leaves a certain loophole in the foundations of formal verification. Namely, by the Goedel Incompleteness Theorem an extension of a verification system by a verified rule generally speaking is not equivalent to the original system. This model leads to a "reflection tower" of metatheories of increasing proof-theoretical strength which itself cannot be verified formally. One has to believe in correctness of a verification system the way we believe in consistency of a set theory.

Riecke, Bell Laboratories, Lucent Technologies Abstract: Over twenty years have past since Denning's original work on security of *values* during computation. Denning, and others following her, worked in imperative languages, and used "flow of information" as the primary mechanism for tracking security. We rework and adapt some of these ideas in the context of the programs, written in the typed lambda calculus, that communicate via shared variables. In this language, we can track more accurately the flow of information. This is joint work with Nevin Heintze. A word of caution: the work is very preliminary! For those among us who have been looking for preliminary work that might allow more discussions, this seems to be a good opportunity :-) Prev: PL seminar - Michael Benedikt, Bell Labs, Web Prog.

Patterns and Compositionality btanksley@hifn.com btanksley@hifn.com Mon, 31 Jan 2000 13:46:53 -0800 Previous message: Patterns and Compositionality Next message: Joy, Lambdas, Combinators, Procedures Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] From: Francois-Rene Rideau [mailto: fare@tunes.org I didn't say it was easy with lambda-like formal calculi. I said it was as easy/difficult with such calculi as with any formal calculi, including sequent calculi that you like. Imperative programming IS a nightmare, stop. Using an imperative calculus as a "primitive" calculus is an abstraction inversion. Not easily. The semantics of computers and turing machines is quite contorted. So are proof sketches in frameworks such as the one used by Coq. The part that's not straightforward is going from the proof sketch to the precise, machine-checkable proof. Having worked with proof checkers for an imperative framework (B, a dialect of Z), I can tell that the latter is certainly not simpler. Not everything. But everything that can be usefully used

Our Program Appendix: Source Code Appendix A - source code for the Dictionary module. Appendix B - source code for the Words module. Appendix C - source code for the Fixwords module. 1. Introduction to Haskell Haskell is a general purpose, purely functional programming language incorporating many recent innovations in programming language design. Haskell provides higher-order functions, non-strict semantics, static polymorphic typing, user-defined algebraic datatypes, pattern-matching, list comprehensions, a module system, a monadic I/O system, and a rich set of primitive datatypes, including lists, arrays, arbitrary and fixed precision integers, and floating-point numbers. Haskell is both the culmination and solidification of many years of research on lazy functional languages. True, this definition is a bit long, but it almost completely shows the power that Haskell has as both a functional language, and as a programming language in general. Because Haskell is a purely functional language is has certain characteristics, and also because Haskell is modern language, many historical mistakes made with language design have been avoided. Recent advances in Typed-Lambda Calculus have formed a basis for Haskell, and the addition of very strong typing to a functional language makes Haskell (unlike LISP) "safe" to use. The typing rules also allow a program Haskell to be validated.

Research articles "An approach to call-by-name delimited continuations" ACM for your personal use - not for redistribution) errata bibtex entry Abstract: It has been shown by Saurin that de Groote's variant of Parigot's lambda-mu-calculus is strictly more expressive in the untyped case than Parigot's original calculus. We show that this additional expressivity exactly corresponds to adding delimited control so that de Groote's calculus can be seen as the exact call-by-name counterpart of Danvy and Filinski's shift-reset calculus. This "duality" is expressed in the lambda-mu-tp-hat-calculus which is lambda-mu-calculus equipped with a single dynamically-bound continuation variable denoting a resettable toplevel. An equational correspondence having already been proved in A type-theoretic foundation of delimited continuations for call-by-value lambda-mu-tp-hat and Danvy and Filinski's calculus, we simply show here the equivalence between call-by-name lambda-mu-tp-hat and de Groote's calculus. We continue with a comparative study of the operational semantics, continuation-passing-style semantics, and simple typing of both call-by-name and call-by-value versions. Finally, we show the existence of two other canonical calculus of delimited continuations. The first one morally forms an equational correspondance with Sabry's shift/lazy-reset calculus while the second one is a "lazy" version of de Groote's calculus.

Veldman Prerequisites: Some familiarity with mathematical reasoning. Literature: C.C. Chang, H.J. Keisler, Model Theory, North Holland Publ. Co. 1977 W. Hodges, Model Theory, Cambridge UP, 1993 Contents: Model theory studies the variety of mathematical structures that satisfy given formal theory. It may also be described as a study of mathematical structures from the logician's point of view. Model theory at its best is a delightful blend of abstract and concrete reasoning. Among the topics to be treated in this course are Fraisse's characterisation of the notion 'elementary equivalence' (structures A,B are called elementarily equivalent if they satisfy the same first-order-sentences), the compactness theorem and its many consequences, ultraproducts, some non-standard-analysis, Tarski's decision method for the field of real numbers by quantifier elimination and Robinson's notion of model completeness. If time permits, some attention will be given to constructive and recursive model theory.
