Abstract
Benettin’s classical method for the calculation of the Lyapunov exponent spectra of smooth flows is applied to the case of systems with elastic hard collisions. As illustrative examples the maximum Lyapunov exponent is calculated for the two-dimensional periodic Lorentz gas over a wide density range, and for the Sinai stadium billiard.
