On the spectrum of a stationary problem with nonlocal integral type boundary condition

open access: yesLietuvos Matematikos Rinkinys, 2004
We investigated a eigenvalue problem for simple second order ordinary differential equation with one inte­gral type nonlocal boundary condition. The eigenvalues and eigenfunctions of such problem are depending on few parameters in the nonlocal boundary ...

Reaction–diffusion equation with nonlocal boundary condition subject to PID-controlled bioreactor

open access: yesNonlinear Analysis, 2017
We study a system of two parabolic nonlinear reaction–diffusion equations subject to a nonlocal boundary condition. This system of nonlinear equations is used for mathematical modeling of biosensors and bioreactors.

A representative solution to m-order linear ordinary differential equation with nonlocal conditions by green's functional concept

open access: yesMathematical Modelling and Analysis, 2012
In this work, we investigate a linear completely nonhomogeneous nonlocal multipoint problem for an m-order ordinary differential equation with generally variable nonsmooth coefficients satisfying some general properties such as p-integrability and ...

Effects of topological boundary conditions on Bell nonlocality

open access: yesPhysical Review A
Bell nonlocality is the resource that enables device-independent quantum information processing tasks. It is revealed through the violation of so-called Bell inequalities, indicating that the observed correlations cannot be reproduced by any local hidden variable model.
