Convergence of multi-dimensional quantized $SDE$'s
Résumé
We quantize a multidimensional $SDE$ (in the Stratanovich sense) by solving the related $ODE$'s in which the Brownian motion has been replaced by the components of stationary quantizers. We make a connection with rough path theory to show that such quantizations converge toward the solution of the $SDE$. In some particular cases, we show that this procedure provide some rate optimal quantizations of the equation.
