Abstract
We consider strong one-point approximation of solutions of scalar stochastic differential equations (SDEs) with irregular coefficients. The drift coefficient a : [0, T] x R -> R is assumed to be Lipschitz continuous with respect to the space variable but only measurable with respect to the time variable. For the diffusion coefficient b : [0, T] -> R we assume that it is only piecewise Holder continuous with Holder exponent Q is an element of (0,1]. We show that, roughly speaking, the error of any algorithm, which uses n values of the diffusion coefficient, cannot converge to zero faster than n(-min)[Q, 1/2] as n -> +infinity. This best speed of convergence is achieved by the randomized Euler scheme. (C) 2015 Elsevier B.V. All rights reserved.
