Concentrating solutions in a two-dimensional elliptic problem with exponential Neumann data
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2005)
We consider the elliptic equation -Delta u+u=O in a bounded, smooth domain ohm in R(2) subject to the nonlinear Neumann boundary condition delta u/delta v = epsilon e(u). Here epsilon > 0 is a small parameter. We prove ...
Multiple solutions of boundary value problems on time scales for a φ-Laplacian operator
(AGH University of Science and Technology, 2020-06)
We establish the existence and multiplicity of solutions for some boundary value problems on time scales with a ϕ-Laplacian operator. For this purpose, we employ the concept of lower and upper solutions and the Leray–Schauder ...
On a Ermakov-Painlevé II reduction in three-ion electrodiffusion: a Dirichlet boundary value problem
(Amer Inst Mathematical Sciences, 2015-08)
Two-point boundary value problems of Dirichlet type are investigated for a ErmakovPainlev´e II equation which arises out of a reduction of a three-ion electrodiffusion Nernst-Planck model system. In addition, it is shown ...
A new elliptic mixed boundary value problem with (p,q)-Laplacian and Clarke subdifferential: Existence, comparison and convergence results
(World Scientific, 2021-12)
The goal of this paper is to investigate a new class of elliptic mixed boundary value problems involving a nonlinear and nonhomogeneous partial differential operator (p,q)-Laplacian, and a multivalued term represented by ...
Lobatto deferred correction for stiff two-point boundary value problems
(Elsevier B.V., 1998-11-01)
An iterated deferred correction algorithm based on Lobatto Runge-Kutta formulae is developed for the efficient numerical solution of nonlinear stiff two-point boundary value problems. An analysis of the stability properties ...
Partial Differential Equations for Missing Boundary Conditions in the Linear-Quadratic Optimal Control Problem
(Planta Piloto de Ingeniería Química, 2009-12)
New equations involving the unknown final states and initial costates corresponding to families of LQR problems are found, and their solutions are computed and validated. Having the initial values of the costates, the ...
Concentrated terms and varying domains in elliptic equations: Lipschitz case
(Wiley-Blackwell, 2016)
In this paper, we analyze the behavior of a family of solutions of a nonlinear elliptic equation with nonlinear boundary conditions, when the boundary of the domain presents a highly oscillatory behavior, which is uniformly ...
Boundary value problems for anisotropic plates with internal line hinges
(Springer Wien, 2012-01)
This paper deals with the formulation of an analytical model for the dynamic behaviour of anisotropic plates, with an arbitrary located interal line hinge with elastics supports and piecewise-smooth boundaries elastically ...
Three-point boundary value problems in Banach spaces
(Springer, 2019-07)
Using degree for α-condensing maps, we obtain the existence of at least one solution for nonlinear boundary value problems {(φ(u′))′=f(t,u,u′)u(0)=u(1)=u′(0),where φ: X→ X is a linear homeomorphism, f: [0 , 1] × X× X→ X ...
