Finite Difference Schemes as Algebraic Correspondences between Layers

EPJ Web of Conferences, 2018
For some differential equations, especially for Riccati equation, new finite difference schemes are suggested. These schemes define protective correspondences between the layers.

Temporal and spatial inconsistencies of time-split finite-difference schemes [PDF]

The properties of an implicit time-split algorithm, which utilizes locally one dimensional spatial steps, are examined using the two-dimensional heat conduction equation as the test problem.

Numerical modeling of high-energy ion implantation using Fokker – Planck equations

Журнал Белорусского государственного университета: Математика, информатика, 2018
The model of transport for high energetic ions in solids based on numerical solving of the boundary value problem for the Fokker – Planck equation is considered. The Fokker – Planck equation has a second order both on energetic and angular variables.

On stability of nonlinear difference equations and some of their applications

Қарағанды университетінің хабаршысы. Математика сериясы
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 priori ...

Well-posedness of fractional parabolic differential and difference equations with Dirichlet-Neumann conditions

Electronic Journal of Differential Equations, 2014
We study initial-boundary value problems for fractional parabolic equations with the Dirichlet-Neumann conditions. We obtain a stable difference schemes for this problem, and obtain theorems on coercive stability estimates for the solution of the ...

ON SOME PROBLEMS OF THERMAL CONDUCTIVITY OF UNIDIRECTIONALLY REINFORCED MATERIALS

Вестник Кемеровского государственного университета, 2014
Structural model of thermal conductivity of unidirectionally reinforced layer is under consideration. The assumption that temperatures are equal within represented element of reinforced layer is addressed in the present research.
