2005-11-03BuchAsymptotic mean-square stability of two-step methods for stochastic ordinary differential equations Buckwar, Evelyn; Horváth-Bokor, Rosza; Winkler, RenateWe deal with linear multi-step methods for SDEs and study when the numerical appro\-xi\-mation shares asymptotic properties in the mean-square sense of the exact solution. As in deterministic numerical analysis we use a ...

2005-11-02BuchImproved linear multi-step methods for stochastic ordinary differential equations Buckwar, Evelyn; Winkler, RenateWe consider linear multi-step methods for stochastic ordinary differential equations and study their convergence properties for problems with small noise or additive noise. We present schemes where the drift part is ...

2005-11-03BuchMulti-step Maruyama methods for stochastic delay differential equations Buckwar, Evelyn; Winkler, RenateIn this paper the numerical approximation of solutions of It{\^o} stochastic delay differential equations is considered. We construct stochastic linear multi-step Maruyama methods and develop the fundamental numerical ...

2005-11-03BuchMulti-step methods for SDEs and their application to problems with small noise Buckwar, Evelyn; Winkler, RenateIn this paper the numerical approximation of solutions of Ito stochastic differential equations is considered, in particular for equations with a small parameter $\epsilon$ in the noise coefficient. We construct stochastic ...

2005-10-12BuchNoise Induced Oscillation in Solutions of Stochastic Delay Differential Equations Appleby, John A. D.; Buckwar, EvelynThis paper studies the oscillatory properties of solutions of linear scalar stochastic delay differential equations with multiplicative noise. It is shown that such noise will induce an oscillation in the solution whenever ...

2005-11-03BuchOn Halanay-type analysis of exponential stability for the theta-Maruyama method for stochastic delay differential equations Baker, Christopher T. H.; Buckwar, EvelynUsing an approach that has its origins in work of Halanay, we consider stability in mean square of numerical solutions obtained from the theta-Maruyama discretization of a test stochastic delay differential equation dX(t) ...

2005-11-03BuchOne-Step Approximations For Stochastic Functional Differential Equations Buckwar, EvelynWe consider the problem of strong approximations of the solution of It\^{o} stochastic functional differential equations (SFDEs). We develop a general framework for the convergence of drift-implicit one-step schemes to the ...
