The tri-harmonic Neumann problem

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2018
In this article investigated the tri-harmonic Neumann function for the unit dics. For harmonics functions the Neumann’s boundary problem is well studied and solved under certain conditions through Neumann’s function, sometimes it is also called Green’s ...

Dirichlet and Neumann Boundary Value Problems for Dunkl Polyharmonic Equations

open access: yesMathematics, 2023
Dunkl operators are a family of commuting differential–difference operators associated with a finite reflection group. These operators play a key role in the area of harmonic analysis and theory of spherical functions.

Three Weak Solutions for an Anisotropic Variable Exponent Problem with Neumann Boundary Condition [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2022
In the present work, we investigate an interval of real parameters $ \lambda $ for which the problem admits at least one nontrivial solution. Moreover we deal with the existence results of three solutions for anisotropic problems with variable exponents.

Three spectra problem for Stieltjes string equation and Neumann conditions

open access: yesPracì Mìžnarodnogo Geometričnogo Centru, 2019
Spectral problems are considered which appear in description of small transversal vibrations of Stieltjes strings. It is shown that the eigenvalues of the Neumann-Neumann problem, i.e.

Applications of the generalised Dirichlet integral inequality to the Neumann problem with fast-growing continuous data

open access: yesJournal of Inequalities and Applications, 2016
By using the generalised Dirichlet integral inequality with continuous functions on the boundary of the upper half-space, we prove new types of solutions for the Neumann problem with fast-growing continuous data on the boundary.

Two-parameter nonlinear oscillations: the neumann problem

open access: yesMathematical Modelling and Analysis, 2011
Boundary value problems of the form  are considered, where  In our considerations functions f and g are generally nonlinear. We give a description of a solution set of the problem (i), (ii). It consist of all triples () such that (λ,μ,x(t)) nontrivially ′

Inhomogeneous parabolic Neumann problems [PDF]

open access: yesCzechoslovak Mathematical Journal, 2014
We study second order parabolic equations on Lipschitz domains subject to inhomogeneous Neumann (or, more generally, Robin) boundary conditions. We prove existence and uniqueness of weak solutions and their continuity up to the boundary of the parabolic cylinder.

Recovering the shape of an equilateral quantum tree with the Dirichlet conditions at the pendant vertices [PDF]

open access: yesOpuscula Mathematica
We consider two spectral problems on an equilateral rooted tree with the standard (continuity and Kirchhoff's type) conditions at the interior vertices (except of the root if it is interior) and Dirichlet conditions at the pendant vertices (except of the
