Stability of the Stochastic θ-Method for Super-Linear Stochastic Differential Equations with Unbounded Delay

open access: yesJournal of Computational Mathematics, 2019
This paper deals with numerical stability properties of super-linear stochastic differential equations with unbounded delay. Sufficient conditions for mean square and almost sure decay stability of the above system and its stochastic θ-method ...

Variations in the geometry of the basins of escape in a modified Hénon–Heiles potential

open access: yesDemonstratio Mathematica
In this article, we show how the curves that limit the basins of escape in a version of a Hénon–Heiles potential with a singularity at the origin evolve with the energy.

The Weighted Square Integral Inequalities for Smooth and Weak Subsolution of Fourth Order Laplace Equation

open access: yesOpen Journal of Mathematical Sciences, 2018
In this work we develop the weighted square integral estimates for the second derivatives of weak subsolution of forth order Laplace equation. It is natural generalization of inequalities develop for the Superharmonic functions in [1].

Blended General Linear Methods based on Boundary Value Methods in the GBDF family [PDF]

open access: yes, 2009
Among the methods for solving ODE-IVPs, the class of General Linear Methods (GLMs) is able to encompass most of them, ranging from Linear Multistep Formulae (LMF) to RK formulae.

Generalised Backward Differentiation Formulae for Fractional Differential Equation

open access: yesEast Asian Journal on Applied Mathematics, 2019
A new approach to construction of generalised backward differentiation formulae for fractional differential equations is proposed. The consistence and convergence of the method are considered and numerical simulations are presented.

A parameter uniform fitted mesh method for a weakly coupled system of two singularly perturbed convection-diffusion equations [PDF]

open access: yes, 2018
In this paper, a boundary value problem for a singularly perturbed linear system of two second order ordinary differential equations of convection- diffusion type is considered on the interval [0, 1]. The components of the solution of this system exhibit

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

A Numerical Method for SDEs with Discontinuous Drift

open access: yes, 2015
In this paper we introduce a transformation technique, which can on the one hand be used to prove existence and uniqueness for a class of SDEs with discontinuous drift coefficient.
