Nonlocal Parabolic Boundary-Value Problems with Singularities

Journal of Mathematical Sciences, 2015
The paper deals with the first boundary value problem and a unilateral boundary value problem with a nonlocal condition with respect to the time variable for a linear differential equation with power singularities of arbitrary order in the coordinate planes. The problems are considered in Hölder spaces with power weight.

Results on Nonlocal Boundary Value Problems

Numerical Functional Analysis and Optimization, 2010
In this article, we provide a variational theory for nonlocal problems where nonlocality arises due to the interaction in a given horizon. With this theory, we prove well-posedness results for the weak formulation of nonlocal boundary value problems with Dirichlet, Neumann, and mixed boundary conditions for a class of kernel functions.

Singular nonlocal boundary value problems

Nonlinear Analysis: Theory, Methods & Applications, 2005
Abstract This paper presents conditions for the existence of solutions to the differential equation ( g ( x ′ ) ) ′ = f ( t , x , x ′ ) satisfying the nonlocal boundary conditions min { x ( t ) : 0 ⩽ t ⩽ T } = 0 and Φ ( x ′ ) = 0 .

Nonlocal Fractional Boundary Value Problems with Slit-Strips Boundary Conditions

Fractional Calculus and Applied Analysis, 2015
In this paper, nonlocal boundary value problems of fractional differential equations and inclusions with slit-strips integral boundary conditions are investigated. Precisely, the existence and uniqueness of the solution for the single valued case is proved and the existence of solutions for the multivalued case is established. One of the main tool with

Nonlocal boundary-value problem for parabolic equations

Ukrainian Mathematical Journal, 1994
Summary: The problem with nonlocal time conditions and periodicity conditions in space variables for Shilov parabolic equations of arbitrary order with constant coefficients is studied. Conditions of existence and uniqueness of a classical solution of the problem are established. The metric theorems on lower bounds of small denominators which appear in

Nonlocal boundary value problem for telegraph equations

AIP Conference Proceedings, 2015
In this work, the nonlocal boundary value problem for a telegraph equation in a Hilbert space is conceived. Stability estimates for the solution of this problem are obtained. The first and second order of accuracy difference schemes for the approximate solution of this problem are constructed.

Positive solutions of nonlocal fractional boundary value problem involving Riemann–Stieltjes integral condition

Journal of Applied Mathematics and Computation, 2020
In this paper, we investigate the existence of positive solutions for a nonlocal fractional boundary value problem involving Caputo fractional derivative and nonlocal Riemann–Stieltjes integral boundary condition.
