A two-level logic perspective on (simultaneous) substitutions [PDF]

open access: greenProceedings of the 7th ACM SIGPLAN International Conference on Certified Programs and Proofs - CPP 2018, 2018
Lambda-tree syntax (λts), also known as higher-order abstract syntax (hoas), is a representational technique where the pure λ-calculus in a meta language is used to represent binding constructs in an object language. A key feature of λts is that capture-avoiding substitution in the object language is represented by β-reduction in the meta language ...

On the Closure of Description Logics under Substitutions

open access: green, 2016
We investigate the extension of Description Logics (DL) with a notion of "substitution". Substitutions naturally arise when reasoning about programs which modify graph structures that are characterized by DLs. They constitute also a means to express concept and role modifications such as addition or deletion of individuals (respectively, pairs of ...

Explicit substitutions, logic and normalization

open access: green, 2004
Les substitutions explicites ont été introduites comme un raffinement du lambda-calcul, celui-ci étant leformalisme utilisé pour étudier la sémantique des langages de programmation. L'objet de cette thèseest l'étude de leurs propriétés de normalisation forte et de préservation de la normalisation forte.

Logic Programming, Substitutions and Finite Computability

open access: hybridDAIMI Report Series, 1985
<p>Apt and van Emden have studied the semantics of logic programming by means of fixed point methods. From a model theoretic point of view, their formalisation is very nice. Least and greatest fixed points correspond to least and greatest Herbrand-models respectively.</p><p>Viewed operationally, there is an ugly asymmetry.

Controllable p‐Type Doping of 2D WSe2 via Vanadium Substitution [PDF]

open access: yesAdvanced Functional Materials, 2021
Scalable substitutional doping of 2D transition metal dichalcogenides is a prerequisite to developing next‐generation logic and memory devices based on 2D materials. To date, doping efforts are still nascent. Here, scalable growth and vanadium (V) doping

Hereditary Substitution for the λΔ-Calculus [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2013
Hereditary substitution is a form of type-bounded iterated substitution, first made explicit by Watkins et al. and Adams in order to show normalization of proof terms for various constructive logics.
