SUMMARY:Clues from the late-time boundary of de Sitter - Gizem Şengör (C
 EICO)

DESCRIPTION:In this talk we will introduce operators at the late-time boun
 dary of de Sitter that capture the late time physics of scalar fields\, an
 d focus on their two-point functions. We will refer to these operators as 
 late-time operators. We will discuss certain properties which make them re
 cognizable as the unitary irreducible representations of the de Sitter gro
 up SO(d+1\,1)\, and their contribution to scalar field and conjugate momen
 tum two-point functions computed using both wavefunction and canonical qua
 ntization methods. By focusing on these late-time operators and their corr
 elation functions our goal is to gather clues about the holographic aspect
 s of de Sitter spacetime guided by group theoretical notions.
