Abstract

The kinetic theory of gases provides methods for calculating Lyapunov exponents
and other quantities, such as Kolmogorov-Sinai entropies, that characterize
the chaotic behavior of hard-ball gases. Here we illustrate the use of
these methods for calculating the Kolmogorov-Sinai entropy, and the largest
positive Lyapunov exponent, for dilute hard-ball gases in equilibrium. The
calculation of the
