Existence of the solution to a nonlocal-in-time evolutional problem [PDF]

open access: yesNonlinear Analysis, 2014
This work is devoted to the study of a nonlocal-in-time evolutional problem for the first order differential equation in Banach space. Our primary approach, although stems from the convenient technique based on the reduction of a nonlocal problem to its ...

Existence of a Period-Two Solution in Linearizable Difference Equations [PDF]

open access: yesDiscrete Dynamics in Nature and Society, 2013
Consider the difference equation xn+1=f(xn,…,xn−k),n=0,1,…, where k∈{1,2,…} and the initial conditions are real numbers. We investigate the existence and nonexistence of the minimal period-two solution of this equation when it can be rewritten as the ...

On some analogues of periodic problems for Laplace equation with an oblique derivative under boundary conditions [PDF]

open access: yesE-Journal of Analysis and Applied Mathematics, 2020
In this paper, we study solvability of new classes of nonlocal boundary value problems for the Laplace equation in a ball. The considered problems are multidimensional analogues (in the case of a ball) of classical periodic boundary value problems in ...

Existence of a solution of the quasi-variational inequality with semicontinuous operator [PDF]

open access: yesYugoslav Journal of Operations Research, 2006
The paper considers quasi-variational inequalities with point to set operator. The existence of a solution, in the case when the operator of the quasi-variational inequality is semi-continuous and the feasible set is convex and compact, is proved.

Existence of Solutions for a Nonlinear Algebraic System [PDF]

open access: yesDiscrete Dynamics in Nature and Society, 2009
As well known, the existence and nonexistence of solutions for nonlinear algebraic systems are very important since they can provide the necessary information on limiting behaviors of many dynamic systems, such as the discrete reaction‐diffusion equations, the coupled map lattices, the compartmental systems, the strongly damped lattice systems, the ...

Existence of solutions of a nonlinear differential equation [PDF]

open access: yesProceedings of the American Mathematical Society, 1983
A criterion is proved for the existence of at least one solution to the equation u + u = g ( u ) + h u + u = g(u) + h with u ( 0 ) = u ( π ) = 0 u(0) = u(\pi ) = 0 , where

Existence of solutions to a diffusive shallow medium equation [PDF]

open access: yesJournal of Evolution Equations, 2020
AbstractIn this article, we establish the existence of weak solutions to the shallow medium equation. We proceed by an approximation argument. First, we truncate the coefficients of the equation from above and below. Then, we prove convergence of the solutions of the truncated problem to a solution to the original equation.
