الالتزام بالمذاهب الأربعة بين الانضباط والجمود - تحليل ومقارنة

open access: yesMarifetname, 2022
من المعلوم في أصول الفقه أنَّ المكلَّف إما أن يكون مجتهداً أو مقلِّداً، فالأول هو القادر على استنباط الأحكام الشرعية من أدلتها مباشرةً، وهذا واجبهُ الاجتهاد، والثاني هوالعاجز عن استنباط الأحكام من أدلتها، وهذا عليه أن يقلِّد اﻟﻤﺠتهدين، وقد شاع بين ...

Regularity for Semilinear Neutral Hyperbolic Equations with Cosine Families

open access: yesMathematics, 2020
The purpose of this paper is to obtain the regularity for solutions of semilinear neutral hyperbolic equations with the nonlinear convolution. The principal operator is the infinitesimal generator of a cosine and sine families.

A Fourier Analysis Based New Look at Integration

open access: yesAnnales Mathematicae Silesianae, 2023
We approach the problem of integration for rough integrands and integrators, typically representing trajectories of stochastic processes possessing only some Hölder regularity of possibly low order, in the framework of para-control calculus.

Modeling the dynamic semantics of a computer program

open access: yesЦифровые модели и решения, 2023
In this paper, two approaches are used to construct the dynamic semantics of computer programs: the first is the representation of mathematical models of computational processes generated by a computer program in the form of a discrete transformer; the ...

Maximal Regularity [PDF]

open access: yes, 2021
AbstractIn this chapter, we address the issue of maximal regularity. More precisely, we provide a criterion on the ‘structure’ of the evolutionary equation $$\displaystyle \left (\overline {\partial _{t,\nu }M(\partial _{t,\nu })+A}\right )U=F $$

Local and Global Existence and Uniqueness of Solution for Time-Fractional Fuzzy Navier–Stokes Equations

open access: yesFractal and Fractional, 2022
Navier–Stokes (NS) equation, in fluid mechanics, is a partial differential equation that describes the flow of incompressible fluids. We study the fractional derivative by using fractional differential equation by using a mild solution.
