Abstract
The Lyapunov exponents and the Kolmogorov Sinai entropy for 2- and 3-d imensional, dilute, random Lorentz gases in a magnetic field are calcu lated. The results are obtained by combining simple kinetic theory wit h geometric methods from dynamical systems theory. The Lyapunov expone nts are explicitly calculated up to second order in the magnetic field .
