On differential operators an differential equations on torus
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2018 In this paper, we consider periodic boundary value problems for a differential equation whose coefficients are trigonometric polynomials. The spaces of generalized functions are constructed, in which the problems considered have solutions, in particular,

The Simple Rings of Differential Operators [PDF]
مجلة التربية والعلم, 2006 In this work, we propose the rings of differential operators are simple and for this proposition we can generalize the results of Jones in 1995. In fact, this work is complement to the results of Mahmood in 2006.

Sobolev-Slobodeckij Spaces on Compact Manifolds, Revisited
Mathematics, 2022 In this manuscript, we present a coherent rigorous overview of the main properties of Sobolev-Slobodeckij spaces of sections of vector bundles on compact manifolds; results of this type are scattered through the literature and can be difficult to find. A

On Recovering Differential Operators on a Closed Set from Spectra [PDF]
Известия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2019 The Sturm – Liouville differential operators on closed sets of the real line are considered. Properties of their spectral characteristics are obtained and the inverse problem of recovering the operators from their spectra is studied. An algorithm for the

Extensions of dissipative operators with closable imaginary part [PDF]
Opuscula Mathematica, 2021 Given a dissipative operator \(A\) on a complex Hilbert space \(\mathcal{H}\) such that the quadratic form \(f \mapsto \text{Im}\langle f, Af \rangle\) is closable, we give a necessary and sufficient condition for an extension of \(A\) to still be ...

Depth estimation of spherical bodies using Differential Operators (Gradient PgP r , Laplacian ر2Z and Biharmonic ر4Z ) to its gravity fields. [PDF]
مجلة جامعة الانبار للعلوم الصرفة, 2012 Differential Operators (Gradient, Laplacian and Biharmonic) have been used to determine anomaly characteristics using theoretical gravity field for spherical bodies with different depths, radius and density contrasts. The intersection between the gravity

Neural operators for accelerating scientific simulations and design [PDF]
Nature Reviews Physics, 2023 Scientific discovery and engineering design are currently limited by the time and cost of physical experiments. Numerical simulations are an alternative approach but are usually intractable for complex real-world problems.

Pseudo-differential operators on Orlicz modulation spaces
, 2023 We deduce continuity properties for pseudo-differential operators with symbols in quasi-Banach Orlicz modulation spaces when rely on other quasi-Banach Orlicz modulation spaces.
