ABSTRACT
We analyze the behavior of the stochastic Lorentz gas in the presence of a force fi eld and we show how can be rigorously proved that certain (very smooth) fields prevent the process obtained by the Boltzmann-Grad limit from being Markovian. The markovianity of the limit can be recovered by introducing a slightly diff erent
setting which allows this difficulty to be removed.
