A symmetrized Euler scheme for an efficient approximation of reflected diffusions
Mireille Bossy, Emmanuel Gobet, Denis Talay · Journal of Applied Probability · 2004
In this article, we analyse the error induced by the Euler scheme combined with a symmetry procedure near the boundary for the simulation of diffusion processes with an oblique reflection on a smooth boundary. This procedure is easy to implement and, in addition, accurate: indeed, we prove that it yields a weak rate of convergence of order 1 with respect to the time-discretization step.
