A nonlocal boundary problem for the Laplace operator in a half disk

Autor: Gani A. Besbaev, Isabek Orazov, Makhmud A. Sadybekov

Publikováno v: Electronic Journal of Differential Equations, Vol 2014, Iss 203,, Pp 1-5 (2014)

In the present work we investigate the nonlocal boundary problem for the Laplace equation in a half disk. The difference of this problem is the impossibility of direct applying of the Fourier method (separation of variables). Because the correspon

Publikováno v: PHYSICO-MATHEMATICAL SERIES. 2:17-36

In this paper, by the method of the deviating argument, we obtain an asymptotic expansionof the solution of the Cauchy problem for an ordinary differential equation of െ th order with variablecoefficients, with an estimate of the residual term thro

On the solvability of a nonlocal boundary value problem for the Laplace operator with opposite flows at the part of the boundary

Autor: Isabek Orazov, Gulnar Dildabek

Publikováno v: AIP Conference Proceedings.

In the present paper, we investigate a nonlocal boundary problem for the Laplace equation in a half-disk, with opposite flows at the part of the boundary. The difference of this problem is the impossibility of direct applying of the Fourier method (s

Solution of a singularly perturbed Cauchy problem using a method of a deviating argument

Autor: Isabek Orazov, Manat Shomanbayeva, Amir Shaldanbayev

Publikováno v: AIP Conference Proceedings.

This paper proposes a principally new method to investigate singularly perturbed Cauchy problem based on the spectral theory of equations with deviating argument. We have got the asymptotic decomposition of solutions of the Cauchy problem for the ord

On an inverse problem of mathematical modeling of the extraction process of polydisperse porous materials

Autor: Makhmud A. Sadybekov, Isabek Orazov

Publikováno v: AIP Conference Proceedings.

In this paper, we consider one family of problems simulating the determination of target components and density of sources from given values of the initial and final states. The mathematical statement of these problems leads to the inverse problem fo
