Abstract
Using an exact, recently obtained solution of the non-linear Boltzmann equation for a particular type of molecular interaction, the authors show that the corresponding second time derivative of the entropy remains negative during the passage to equilibrium. The signs of higher derivatives are considered.Keywords
