Which Arithmetical Data Types Admit Fracterm Flattening?

open access: yesScientific Annals of Computer Science, 2022
The formal theory of division in arithmetical algebras reconstructs fractions as syntactic objects called fracterms. Basic to calculation, is the simplification of fracterms to fracterms with one division operator, a process called fracterm ...

Operator Calculus and the Solution of the Equations of Quantum Dynamics

open access: yes, 1926
A formal calculus is developed which includes the Born and Jordan matrix dynamics, and also the remarkable quantum condition of Schroedinger. A method for the calculation of the matrices which is in close analogy to the classical Hamilton-Jacobi method ...

Image Denoising Algorithm Based on Entropy and Adaptive Fractional Order Calculus Operator

open access: yesIEEE Access, 2017
In this paper, a fractional calculus operator for image denoising is constructed based on the characteristic of local entropy and the gradient feature, and an adaptive fractional calculus image denoising algorithm is proposed.

Semilocal convergence of Newton-like methods under general conditions with applications in fractional calculus

open access: yesJournal of Numerical Analysis and Approximation Theory, 2015
We present a semilocal convergence study of Newton-like methods on a generalized Banach space setting to approximate a locally unique zero of an operator.

Restrictions for loop-check in sequent calculus for temporal logic with until operator

open access: yesLietuvos Matematikos Rinkinys, 2009
In this paper, we present sequent calculus for branching-time temporal logic with until operator. This sequent calculus uses efficient loop-checktechinque.

Operator Calculus Approach to Comparison of Elasticity Models for Modelling of Masonry Structures

open access: yesMathematics, 2022
The solution of any engineering problem starts with a modelling process aimed at formulating a mathematical model, which must describe the problem under consideration with sufficient precision. Because of heterogeneity of modern engineering applications,

Magnetic Fourier Integral Operators

open access: yes, 2010
In some previous papers we have defined and studied a 'magnetic' pseudodifferential calculus as a gauge covariant generalization of the Weyl calculus when a magnetic field is present. In this paper we extend the standard Fourier Integral Operators Theory

Newton-Type Methods on Generalized Banach Spaces and Applications in Fractional Calculus

open access: yesAlgorithms, 2015
We present a semilocal convergence study of Newton-type methods on a generalized Banach space setting to approximate a locally unique zero of an operator. Earlier studies require that the operator involved is Fréchet differentiable.
