Generalized Uncertainty Principle, Modified Dispersion Relations and Early Universe Thermodynamics

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/177380In 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.21 Pages, 3 eps Figure, Revised VersionGeneral Relativity and Quantum CosmologyGeneralized Uncertainty Principle, Modified Dispersion Relations and Early Universe Thermodynamicstext
