A non-local problem with integral conditions of the first kind for the string vibration equation

open access: yesВестник Самарского университета: Естественнонаучная серия, 2023
The article considers a problem with integral nonlocal conditions of the first kind. The main goal is to prove the unique solvability of a nonlocal problem with integral conditions of the 1st kind, if the kernels of these conditions depend not only on ...

Formulation, analysis and computation of an optimization-based local-to-nonlocal coupling method

open access: yesResults in Applied Mathematics, 2021
We present an optimization-based coupling method for local and nonlocal continuum models. Our approach couches the coupling of the models into a control problem where the states are the solutions of the nonlocal and local equations, the objective is to ...

A remark on elliptic differential equations on manifold

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2020
For elliptic boundary value problems of nonlocal type in Euclidean space, the well posedness has been studied by several authors and it has been well understood. On the other hand, such kind of problems on manifolds have not been studied yet.
