On stability of nonlinear difference equations and some of their applications
Autor: M.M. Aripov, D. Utebaev, B.D. Utebaev, R.Sh. Yarlashov
Publikováno v: Қарағанды университетінің хабаршысы. Математика сериясы, Vol 115, Iss 3 (2024)
The issues of stability in solving nonlinear difference equations were considered. Based on a generalized difference analog of the well-known Bihari lemma, stability conditions for a trivial solution based on initial data were obtained, and an a prio

On convergence of difference schemes of high accuracy for one pseudo-parabolic Sobolev type equation
Autor: M.M. Aripov, D. Utebaev, M.M. Kazimbetova, R.Sh. Yarlashov
Publikováno v: Қарағанды университетінің хабаршысы. Математика сериясы, Vol 109, Iss 1, Pp 24-37 (2023)
Difference schemes of the finite difference method and the finite element method of high-order accuracy in time and space are proposed and investigated for a pseudo-parabolic Sobolev type equation. The order of accuracy in space is improved in two wa

On the convergence of difference schemes of high accuracy for the equation of ion-acoustic waves in a magnetized plasma
Autor: M.M. Aripov, D. Utebaev, Zh.A. Nurullaev
Publikováno v: Қарағанды университетінің хабаршысы. Математика сериясы, Vol 108, Iss 4, Pp 4-19 (2022)
Multiparametric difference schemes of the finite element method of a high order of accuracy for the Sobolevtype equation of the fourth-order in time are studied. In particular, the first boundary value problem for the equation of ion-acoustic waves i
