A second order convergent trial method for a free boundary problem in three dimensions [PDF]

open access: yes, 2015
The present article is concerned with the solution of a generalized Bernoulli free boundary problem in three spatial dimensions. We parametrize the free boundary under consideration over the sphere and apply a trial method which updates the free boundary

Stabilization of the trial method for the Bernoulli problem in case of prescribed Dirichlet data [PDF]

open access: yes, 2013
We apply the trial method for the solution of Bernoulli’s free boundary problem when the Dirichlet boundary condition is imposed for the solution of the underlying Laplace equation and the free boundary is updated according to the Neumann boundary ...

Trial methods for Bernoulli's free boundary problem [PDF]

open access: yes, 2014
Free boundary problems deal with solving partial differential equations in a domain, a part of whose boundary is unknown – the so-called free boundary. Beside the standard boundary conditions that are needed in order to solve the partial differential ...

Solving the geodesics on the ellipsoid as a boundary value problem

open access: yesJournal of Geodetic Science, 2013
The geodesic between two given points on an ellipsoid is determined as a numerical solution of a boundary value problem. The secondorder ordinary differential equation of the geodesic is formulated by means of the Euler-Lagrange equation of the calculus ...

An inverse three spectra problem for Sturm–Liouville operators

open access: yesBoundary Value Problems, 2018
In this paper, we consider the inverse three spectra problems of recovering the Sturm–Liouville equation by the spectra of the Neumann–Dirichlet boundary value problem on [0,1] $[0,1]$, the Neumann–Robin problem on [0,1/2] $[0,1/2]$, and the Robin ...

A remark on elliptic differential equations on manifold

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2020
For elliptic boundary value problems of nonlocal type in Euclidean space, the well posedness has been studied by several authors and it has been well understood. On the other hand, such kind of problems on manifolds have not been studied yet.

On a method for approximate solution of a mixed boundary value problem for an elliptic equation

open access: yesЖурнал Средневолжского математического общества, 2021
A mixed boundary value problem for an elliptic equation of divergent type with variable coefficients is considered. It is assumed that the integration region is a rectangle, and the boundary of the integration region is the union of two disjoint pieces ...

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 ...
