An Algorithmic Introduction to Numerical Simulation of Stochastic Differential Equations Desmond J. Higham Abstract. INTRODUCTION Numerical methods that are in common use(1 4) for solving stochastic differential equations have a timestep of fixed length, perhaps divided up In the area of "Numerical Methods for Differential Equations", it seems very hard to nd a textbook incorporating mathematical, physical, and engineer-ing issues of numerical methods in a synergistic fashion. The solutions are stochastic processes that represent diffusive dynamics, a common modeling assumption in many application areas. Note a major di erence: while the t0 i in the Riemann integral may be chosen . constructing a numerical method for solving stochastic differential equations. Together with Nicola Bruti-Liberati we had for several years planned a book to follow on the book with Peter Kloeden on the "Numerical Solution of Stochastic Dierential Equations", which rst appeared in 1992 at Springer Verlag and helped to develop the theory and practice of this eld.

So the rst goal of this lecture note is to provide students a convenient textbook that addresses In the present paper we adopt an L2-norm analysis because it can best exhibit the nonanticipating property [1] of the solutions of stochastic differential equations. Our main tools are the fractional calculus and the fourth moment theorem. If the stochastic theta method is $p$th moment exponentially stable for a sufficiently small $p\in (0,1)$, we can then infer that the underlying SDE is almost surely exponentially stable.
