Full Abstraction for the Resource Lambda Calculus with Tests, through Taylor Expansion [PDF]

open access: yesLogical Methods in Computer Science, 2012
We study the semantics of a resource-sensitive extension of the lambda calculus in a canonical reflexive object of a category of sets and relations, a relational version of Scott's original model of the pure lambda calculus.

Presentable signatures and initial semantics [PDF]

open access: yesLogical Methods in Computer Science, 2021
We present a device for specifying and reasoning about syntax for datatypes, programming languages, and logic calculi. More precisely, we study a notion of "signature" for specifying syntactic constructions.

Nominal Coalgebraic Data Types with Applications to Lambda Calculus [PDF]

open access: yesLogical Methods in Computer Science, 2013
We investigate final coalgebras in nominal sets. This allows us to define types of infinite data with binding for which all constructions automatically respect alpha equivalence. We give applications to the infinitary lambda calculus.

Consistency and Completeness of Rewriting in the Calculus of Constructions [PDF]

open access: yesLogical Methods in Computer Science, 2008
Adding rewriting to a proof assistant based on the Curry-Howard isomorphism, such as Coq, may greatly improve usability of the tool. Unfortunately adding an arbitrary set of rewrite rules may render the underlying formal system undecidable and ...

A Bi-Directional Refinement Algorithm for the Calculus of (Co)Inductive Constructions [PDF]

open access: yesLogical Methods in Computer Science, 2012
The paper describes the refinement algorithm for the Calculus of (Co)Inductive Constructions (CIC) implemented in the interactive theorem prover Matita.

A coinductive semantics of the Unlimited Register Machine [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2011
We exploit (co)inductive specifications and proofs to approach the evaluation of low-level programs for the Unlimited Register Machine (URM) within the Coq system, a proof assistant based on the Calculus of (Co)Inductive Constructions type theory.

Monads need not be endofunctors [PDF]

open access: yesLogical Methods in Computer Science, 2015
We introduce a generalization of monads, called relative monads, allowing for underlying functors between different categories. Examples include finite-dimensional vector spaces, untyped and typed lambda-calculus syntax and indexed containers.

A weak HOAS approach to the POPLmark Challenge [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2013
Capitalizing on previous encodings and formal developments about nominal calculi and type systems, we propose a weak Higher-Order Abstract Syntax formalization of the type language of pure System ...

Serial verb constructions and covert coordinations in Edo – an analysis in Type Logical Grammar

open access: yesJournal of Language Modelling, 2021
Based on both syntactic and semantic criteria, Stewart (2001) and, following him, Baker and Stewart (1999), distinguish two types of serial verb constructions (SVC) and one type of covert coordination (CC) in Edo.

Discrete Laplacian Operator and Its Applications in Signal Processing

open access: yesIEEE Access, 2020
Fractional calculus has increased in popularity in recent years, as the number of its applications in different fields has increased. Compared to the traditional operations in calculus (integration and differentiation) which are uniquely defined, the ...
