On the behavior of the bounds of the holographic theory for massive and   massless particle systems
  The aim of the present dissertation is to analyze the meaning of the entropy bounds of the holographic sector once tested for statistical ensembles of particles, in order to deeper investigate the nature of these constraints and their mutual links. From the Universal Energy Bound (UEB) simple time constraints can be argued, which are manifestations of the discrete nature of the space-time and of the presence of ultimate space-time scales. From the combined effort of the UEB and of the Holographic bound by 't Hooft and Susskind, an entropy density bound as a function of temperature is achieved.
