Boundary Value Problems and Boundary Value Spaces [PDF]

, 2021
AbstractThis chapter is devoted to the study of inhomogeneous boundary value problems. For this, we shall reformulate the boundary value problem again into a form which fits within the general framework of evolutionary equations. In order to have an idea of the type of boundary values which make sense to study, we start off with a section that deals ...

Existence result for a Kirchhoff elliptic system with variable parameters and additive right-hand side via sub- and supersolution method

Boundary Value Problems, 2020
The paper deals with the study of the existence result for a Kirchhoff elliptic system with additive right-hand side and variable parameters by using the sub-/supersolution method. Our study is a natural extension result of our previous one in (Boulaaras

Geodesic boundary value problems with symmetry [PDF]

, 2009
This paper shows how left and right actions of Lie groups on a manifold may be used to complement one another in a variational reformulation of optimal control problems equivalently as geodesic boundary value problems with symmetry.

Pseudospectra of Semiclassical Boundary Value Problems [PDF]

, 2014
We consider operators $-\Delta + X$ where $X$ is a constant vector field, in a bounded domain and show spectral instability when the domain is expanded by scaling.

On four-point fractional q-integrodifference boundary value problems involving separate nonlinearity and arbitrary fractional order

Boundary Value Problems, 2018
In this paper, we study a sequential Caputo fractional q-integrodifference equation with fractional q-integral and Riemann–Liouville fractional q-derivative boundary value conditions.

Nonlinear second-order multivalued boundary value problems [PDF]

, 2003
In this paper we study nonlinear second-order differential inclusions involving the ordinary vector $p$-Laplacian, a multivalued maximal monotone operator and nonlinear multivalued boundary conditions.

Lie symmetries of nonlinear boundary value problems [PDF]

, 2012
Nonlinear boundary value problems (BVPs) by means of the classical Lie symmetry method are studied. A new definition of Lie invariance for BVPs is proposed by the generalization of existing those on much wider class of BVPs.

Multiple positive solutions for quasilinear elliptic problems with combined critical Sobolev–Hardy terms

Boundary Value Problems, 2019
In this paper, we investigate the quasilinear elliptic equations involving multiple critical Sobolev–Hardy terms with Dirichlet boundary conditions on bounded smooth domains  Ω⊂RN $\varOmega \subset R^{N}$ ( N≥3 ${N \ge 3} $), and prove the multiplicity ...

The existence of nontrivial solution of a class of Schrödinger–Bopp–Podolsky system with critical growth

Boundary Value Problems, 2020
We consider the following Schrödinger–Bopp–Podolsky problem: { − Δ u + V ( x ) u + ϕ u = λ f ( u ) + | u | 4 u , in  R 3 , − Δ ϕ + Δ 2 ϕ = u 2 , in  R 3 .
