Partial Differential Equations in Applied Mathematics, 2023 This paper presents a uniformly convergent numerical scheme for singularly perturbed fractional order convection–diffusion equations with variable coefficients. First, the time-fractional derivative is considered in the Caputo sense and treated using the

Composite Backward Differentiation Formula for the Bidomain Equations
Frontiers in Physiology, 2020 The bidomain equations have been widely used to model the electrical activity of cardiac tissue. While it is well-known that implicit methods have much better stability than explicit methods, implicit methods usually require the solution of a very large ...

Numerical schemes for 3D parabolic problem with non-local boundwy condition
Lietuvos Matematikos Rinkinys, 2004 Two finite difference schemes are used to solve the 3D parabolic problem with a non-local boundary condition. A new approximation of the initial condition is proposed for the explicit Euler scheme.

A robust uniformly convergent scheme for two parameters singularly perturbed parabolic problems with time delay [PDF]
Iranian Journal of Numerical Analysis and Optimization, 2023 A singularly perturbed time delay parabolic problem with two small pa-rameters is considered. The paper develops a finite difference scheme that is exponentially fitted on a uniform mesh in the spatial direction and uses the implicit-Euler method to ...

Numerical solution of hyperbolic heat conduction equation
Mathematical Modelling and Analysis, 2009 Hyperbolic heat conduction problem is solved numerically. The explicit and implicit Euler schemes are constructed and investigated. It is shown that the implicit Euler scheme can be used to solve efficiently parabolic and hyperbolic heat conduction ...

The spectral discretization of the second-order wave equation
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2022 In this paper we deal with the discretization of the second order wave equation by the implicit Euler scheme for the time and the spectral method for the space. We prove that the time semi discrete and the full discrete problems are well posed.

Analysis of the thermoviscoelastic Timoshenko system with diffusion effect
Partial Differential Equations in Applied Mathematics, 2021 This paper is concerned with a new Timoshenko beam model with thermal, mass diffusion and viscoelastic effects. First, by the C0-semigroup theory, we prove the well posedness of the considered problem with Dirichlet boundary conditions.
