Dual Numbers and Operational Umbral Methods

open access: yesAxioms, 2019
Dual numbers and their higher-order version are important tools for numerical computations, and in particular for finite difference calculus. Based on the relevant algebraic rules and matrix realizations of dual numbers, we present a novel point of view,

The Application of Abstract Algebra in Operational Calculus

open access: yesFractal and Fractional
This paper is dedicated to elucidating the abstract algebraic structure of operational calculus theory. Based on abstract algebra and operational calculus, the operator algebra theory of Mikusiński has been revised. We restate the concept of Mikusiński’s

Classical logic, continuation semantics and abstract machines [PDF]

open access: yes, 1998
One of the goals of this paper is to demonstrate that denotational semantics is useful for operational issues like implementation of functional languages by abstract machines.

Operational calculus and integral transforms for groups with finite propagation speed [PDF]

open access: yes, 2016
Let $A$ be the generator of a strongly continuous cosine family $(\cos (tA))_{t\in {\bf R}}$ on a complex Banach space $E$. The paper develops an operational calculus for integral transforms and functions of $A$ using the generalized harmonic analysis ...

Wave-Style Token Machines and Quantum Lambda Calculi

open access: yes, 2015
Particle-style token machines are a way to interpret proofs and programs, when the latter are written following the principles of linear logic. In this paper, we show that token machines also make sense when the programs at hand are those of a simple ...

A Verified Algebra for Linked Data [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2011
A foundation is investigated for the application of loosely structured data on the Web. This area is often referred to as Linked Data, due to the use of URIs in data to establish links.

Divergence and unique solution of equations [PDF]

open access: yesLogical Methods in Computer Science, 2019
We study proof techniques for bisimilarity based on unique solution of equations. We draw inspiration from a result by Roscoe in the denotational setting of CSP and for failure semantics, essentially stating that an equation (or a system of equations ...

Nonlocal Operational Calculi for Dunkl Operators [PDF]

open access: yes, 2009
The one-dimensional Dunkl operator $D_k$ with a non-negative parameter $k$, is considered under an arbitrary nonlocal boundary value condition. The right inverse operator of $D_k$, satisfying this condition is studied.

Probabilistic Operational Semantics for the Lambda Calculus

open access: yes, 2011
Probabilistic operational semantics for a nondeterministic extension of pure lambda calculus is studied. In this semantics, a term evaluates to a (finite or infinite) distribution of values.

Types for BioAmbients [PDF]

open access: yes, 2010
The BioAmbients calculus is a process algebra suitable for representing compartmentalization, molecular localization and movements between compartments.
