Radial solutions for a nonlocal boundary value problem [PDF]
We consider the boundary value problem for the nonlinear Poisson equation with a nonlocal term −Δu=f(u,∫Ug(u)), u|∂U=0. We prove the existence of a positive radial solution when f grows linearly in u, using Krasnoselskiiés fixed ...

Positivity of Green's matrix of nonlocal boundary value problems [PDF]
Summary: We propose an approach for studying the positivity of Green's operators of a nonlocal boundary value problem for the system of \(n\) linear functional differential equations with the boundary conditions \(n_{i}x_{i}-\sum \nolimits_{j=1}^{n}m_{ij}x_{j}=\beta_{i}\), \(i=1,\dots ,n\), where \(n_{i}\) and \(m_{ij}\) are linear bounded ``local ...

Nonlocal elliptic boundary value problems [PDF]
An m-point nonlocal boundary value problem is posed for quasi- linear differential equations of first order on the plane. Nonlocal boundary value problems are investigated using the algorithm of reducing nonlocal boundary value problems to a sequence of ...

Gradient method in Sobolev spaces for nonlocal boundary-value problems [PDF]
An infinite-dimensional gradient method is proposed for the numerical solution of nonlocal quasilinear boundary-value problems. The iteration is executed for the boundary-value problem itself (i.e.

A Two-Dimensional Nonlocal Fractional Parabolic Initial Boundary Value Problem [PDF]
In this paper, we investigate a two-dimensional singular fractional-order parabolic partial differential equation in the Caputo sense. The partial differential equation is supplemented with Dirichlet and weighted integral boundary conditions.
