DESCRIPTION:Title: <a href="https://researchseminars.org/talk/HETatNTUA/5/
 ">The eigenmodes for spinor quantum field theory in global de Sitter space
 -time</a>\nby Vasileios Letsios (York U.\, Dept. Math.) as part of High En
 ergy Theory\, Gravity  and Cosmology Seminars @ NTUA\n\n\nAbstract\nThe de
  Sitter space-time is famous for being able to describe an expanding Unive
 rse and thus understanding physics in this space-time is of high importanc
 e. It is known that N-dimensional de Sitter space-time can be viewed as an
  ``analytic continuation'' of the N-dimensional sphere. Hence\, given the 
 solutions of the Dirac equation on the N-dimensional sphere\, one can obta
 in the solutions of the Dirac equation in de Sitter space-time by using ap
 propriate techniques. In this talk\, I will briefly explain how one can c
 onstruct a spinor quantum field theory in de Sitter space-time by making u
 se of these techniques. This talk is based on https://arxiv.org/abs/2011.
