Query: Generalized Uncertainty Principle, Modified Dispersion Relations and
  Early Universe Thermodynamics   In this paper, we study the effects of Generalized Uncertainty Principle(GUP)
and Modified Dispersion Relations(MDRs) on the thermodynamics of
ultra-relativistic particles in early universe. We show that limitations
imposed by GUP and particle horizon on the measurement processes, lead to
certain modifications of early universe thermodynamics.
