Fuzzy differential equation with nonlocal conditions and fuzzy semigroup

Advances in Differential Equations, 2016
In this work, we use the fuzzy strongly continuous semigroup theory to prove the existence, uniqueness, and some properties of solutions of fuzzy differential equations with nonlocal conditions.

ON ROOT FUNCTIONS OF NONLOCAL DIFFERENTIAL SECOND-ORDER OPERATOR WITH BOUNDARY CONDITIONS OF PERIODIC TYPE

Вестник КазНУ. Серия математика, механика, информатика, 2021
In this paper we consider one class of spectral problems for a nonlocal ordinary differential operator (with involution in the main part) with nonlocal boundary conditions of periodic type.

Strain Engineering of Magnetoresistance and Magnetic Anisotropy in CrSBr

Advanced Materials, EarlyView.
Biaxial compressive strain significantly enhances magnetoresistance and critical saturation fields in thin flakes of the 2D magnet CrSBr, along all three crystallographic axes. First‐principles calculations link these effects to strain‐induced increases in exchange interactions and magnetic anisotropy.

Spin‐Split Edge States in Metal‐Supported Graphene Nanoislands Obtained by CVD

Advanced Materials, EarlyView.
Combining STM measurements and ab‐initio calculations, we show that zig‐zag edges in graphene nanoislands grown on Ni(111) by CVD retrieve their spin‐polarized edge states after intercalation of a few monolayers of Au. ABSTRACT Spin‐split states localized on zigzag edges have been predicted for different free‐standing graphene nanostructures.

Exact solutions for the static bending of Euler-Bernoulli beams using Eringen’s two-phase local/nonlocal model

AIP Advances, 2016
Though widely used in modelling nano- and micro- structures, Eringen’s differential model shows some inconsistencies and recent study has demonstrated its differences between the integral model, which then implies the necessity of using the latter model.

A Nonlinear Fractional Problem with Mixed Volterra-Fredholm Integro-Differential Equation: Existence, Uniqueness, H-U-R Stability, and Regularity of Solutions

Journal of Function Spaces, 2020
This paper considers nonlinear fractional mixed Volterra-Fredholm integro-differential equation with a nonlocal initial condition. We propose a fixed-point approach to investigate the existence, uniqueness, and Hyers-Ulam-Rassias stability of solutions ...

Nonlocal diffusion second order partial differential equations

Journal of Differential Equations, 2017
The paper deals with the second order integro-differential equation \[ u_{tt}=c u_t+bu(t,\xi)+u(t,\xi)\int_\Omega k(\xi,\eta)u(t,\eta)d\eta +h(t,u(t,\xi)), \] where \(\Omega\subset\mathbb{R}^n,\) \(n\geq2,\) is a \(C^1\)-smooth and bounded domain, \(b\) and \(c\) are constants and \(k: \Omega\times \Omega\to\mathbb{R},\) \(h: [0,T]\times\mathbb{R}\to ...

On some linear two-point inverse problem for a multidimensional heat conduction equation with semi-nonlocal boundary conditions

Қарағанды университетінің хабаршысы. Математика сериясы
It is known that V.A. Ilyin and E.I. Moiseev studied generalized nonlocal boundary value problems for the Sturm-Liouville equation, the nonlocal boundary conditions specified at the interior points of the interval under consideration. For such problems,
