Numerical treatment for the solution of singularly perturbed pseudo-parabolic problem on an equidistributed grid

Nonlinear Engineering, 2020
The initial-boundary value problem for a pseudo-parabolic equation exhibiting initial layer is considered. For solving this problem numerically independence of the perturbation parameter, we propose a difference scheme which consists of the implicit ...

Error analysis of implicit Euler methods for quasilinear hyperbolic evolution systems

, 2016
In this paper we study the convergence of the semi-implicit and the implicit Euler methods for the time integration of abstract, quasilinear hyperbolic evolution equations. The analytical framework considered here includes certain quasilinear Maxwell's and wave equations as special cases.

The Penalty resolution of the spectral element discretization of the time dependent Darcy equations

Boundary Value Problems
The time-dependent Darcy system, when discretized in time using the implicit Euler scheme and in space using the spectral element method, can be efficiently solved using the penalty method.

Comparison of second-order mixed symplectic integrator between semi-implicit Euler method and implicit midpoint rule

Acta Physica Sinica, 2011
When a Hamiltonian can be split into integrable and nonintegrable parts, the former part is solved analytically, and the latter one is integrated numerically by means of implicit symplectic integrators such as the first-order semi-implicit Euler method or the second-order implicit midpoint rule.

A note on almost sure exponential stability of θ-Euler-Maruyama approximation for neutral stochastic differential equations with time-dependent delay when θ ∈ (12{1 \over 2}, 1)

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
This paper is motivated by the paper [2]. The main aim of this paper is to extend the stability result from [16], related to the θ-Euler- Maruyama method (θ ∈ (12{1 \over 2}, 1)) for a class of neutral stochastic differential equations with time ...

Construction of positivity-preserving numerical method for stochastic SIVS epidemic model

Advances in Difference Equations, 2019
In this paper we propose the balanced implicit numerical techniques for maintaining the nonnegative path of the solution in stochastic susceptible–infected–vaccinated–susceptible (SIVS) epidemic model.
