On a class of inverse problems for a heat equation with involution perturbation
Nasser Al-Salti, Mokhtar Kirane, Berikbol T. Torebek
A class of inverse problems for a heat equation with involution perturbation is considered using four different boundary conditions, namely, Dirichlet, Neumann, periodic and anti-p…
Some spectral properties and isoperimetric inequalities for a nonlocal Laplacian problem
Makhmud A. Sadybekov, Berikbol T. Torebek
In this paper we consider a non-local problem for a Laplace operator in a multidimensional bounded symmetric domain. The investigated problem is an analogue of the classical period…
A criterion of solvability of the elliptic Cauchy problem in a multi-dimensional cylindrical domain
Tynysbek Sh. Kalmenov, Makhmud A. Sadybekov, Berikbol T. Torebek
In this paper we consider the Cauchy problem for multidimensional elliptic equations in a cylindrical domain. The method of spectral expansion in eigenfunctions of the Cauchy probl…
A nonlocal fractional Helmholtz equation
Mokhtar Kirane, Batirkhan K. Turmetov, Berikbol T. Torebek
In this paper we study some boundary value problems for a fractional analogue of second order elliptic equation with an involution perturbation in a rectangular domain. Theorems on…
