Abstract

For the solution (Formula presented.) of a Lévy-driven (Formula presented.) -dimensional Marcus (canonical) stochastic differential equation, we prove that the Wong–Zakai approximation scheme (Formula presented.) converges strongly with order (Formula presented.). More precisely, for any (Formula presented.) there exists a constant (Formula presented.) such that (Formula presented.) for all (Formula presented.). We also establish the rate of locally uniform strong convergence: for every (Formula presented.) and any (Formula presented.) there exists a constant (Formula presented.) such that (Formula presented.).
