Conditioning Analysis of Nonlocal Integral Operators in Fractional Sobolev Spaces

open access: yesSIAM Journal on Numerical Analysis, 2014
We study the conditioning of nonlocal integral operators with singular and integrable kernels in fractional Sobolev spaces. These operators are used, for instance, in peridynamics formulation and nonlocal diffusion. In one dimension (1D), we present sharp quantification of the extremal eigenvalues in all three parameters: size of nonlocality, mesh size,

An eigenvalue problem for the differential operator with an integral condition

open access: yesLietuvos Matematikos Rinkinys, 2012
We analyze solution of a two-dimensional parabolic equation with a nonlocal integral condition by a locally one-dimensional method. The main aim of the paper is to deduce stability conditions of a system of one-dimensional equations with one integral ...

Fractional Langevin Equations with Nonlocal Integral Boundary Conditions [PDF]

open access: yesMathematics, 2019
In this paper, we investigate a class of nonlinear Langevin equations involving two fractional orders with nonlocal integral and three-point boundary conditions. Using the Banach contraction principle, Krasnoselskii’s and the nonlinear alternative Leray Schauder theorems, the existence and uniqueness results of solutions are proven.

An inverse boundary value problem for transverse vibrations of a bar

open access: yesBoundary Value Problems, 2022
In this article, we study an inverse problem (IP) for a fourth-order hyperbolic equation with nonlocal boundary conditions. This IP is reduced to the not self-adjoint boundary value problem (BVP) with corresponding boundary condition.
