Algebraic Logic Perspective on Prucnal’s Substitution [PDF]

open access: bronzeNotre Dame Journal of Formal Logic, 2016
A term $\mathit{td}(p,q,r)$ is called a ternary deductive (TD) term for a variety of algebras $\mathcal{V}$ if the identity $\mathit{td}(p,p,r)\approxr$ holds in $\mathcal{V}$ and $(\mathsf{c},\mathsf{d})\in\theta(\mathsf{a},\mathsf{b})$ yields $\mathit{td}(\mathsf{a},\mathsf{b},\mathsf{c})\approx\mathit{td}(\mathsf{a},\mathsf{b},\mathsf{d})$ for any $\

Eliminating the substitution axiom from Unity logic

open access: green, 1990
The UNITY substitution axiom, "if (x=y) is an invariant of a program, then x can be replaced by y in any property of the program", is problematic for several reasons. In this paper, dual predicate transformerssst andwst are introduced that allow the strongest invariant of a program to be expressed, and these are used to give new definitions for the ...

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.

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.

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.
