Abstract
An ab initio theoretical method is derived for calculating the maximal Lyapunov exponent of an N-body system obeying Hamilton's equations. T he theory is developed in detail for a dilute gas. It shows the Lyapun ov exponent to be a function of the time integral of the correlation f unction for fluctuations in the second derivative of the interparticle potential (approximately a power 1/3 law). We apply the theory to a o ne-component plasma and derive the dependence of the Lyapunov exponent on a plasma parameter.
