Uniform convergence on a Bakhvalov-type mesh using the preconditioning approach: Technical report [PDF]

open access: yes, 2015
The linear singularly perturbed convection-diffusion problem in one dimension is considered and its discretization on a Bakhvalov-type mesh is analyzed. The preconditioning technique is used to obtain the pointwise convergence uniform in the perturbation

Two combined methods for the global solution of implicit semilinear differential equations with the use of spectral projectors and Taylor expansions

open access: yes, 2019
Two combined numerical methods for solving semilinear differential-algebraic equations (DAEs) are obtained and their convergence is proved. The comparative analysis of these methods is carried out and conclusions about the effectiveness of their ...

Higher order numerical method for a semilinear system of singularly perturbed differential equations [PDF]

open access: yes, 2021
In this paper, a system of singularly perturbed second order semilinear differential equations with prescribed boundary conditions is considered. To solve this problem, a parameter-uniform numerical method is constructed which consists of a classical ...

Geometry Equilibration of Crystalline Defects in Quantum and Atomistic Descriptions

open access: yes, 2018
We develop a rigorous framework for modelling the geometry equilibration of crystalline defects. We formulate the equilibration of crystal defects as a variational problems on a discrete energy space and establish qualitatively sharp far-field decay ...

Practical implementation and error bounds of integer-type general algorithm for higher order differential equations

open access: yes, 2010
In our preceding paper, we have proposed an algorithm for obtaining finite-norm solutions of higher-order linear ordinary differential equations of the Fuchsian type [\sum_m p_m (x) (d/dx)^m] f(x) = 0 (where p_m is a polynomial with rational-number ...
