By combining the DiPerna and Lions techniques for the nonrelativistic Boltzmann equation and the Dudyński and Ekiel-Jeżewska device of the causality of the relativistic Boltzmann equation, it is shown that there exists a global mild solution to the Cauchy problem for the relativistic Boltzmann equation with the assumptions of the relativistic scattering cross section including some relativistic...

The point of view I take to summarize some of the research activities in Italy in the field of hadronic physics, is determined by the (today accepted) fundamental degrees of freedom of the strong interactions, namely quarks and gluons. The Sec. 2 is devoted to the link of the fundamental theory of strong interactions, Quantum Chromodynamics (QCD), with effective degrees of freedom often used to...
