| 14:00 - 15:00 Weekly Seminar HEPCo Group Towards the framework of averaging in General Relativity School PHYSICS Date and time Tuesday, 11th of July 2023 (20th of Tir, 1402), 2:00 pm (Tehran zone) Link https://www.skyroom.online/ch/schoolofphysics/highenergyseminar Abstract In this talk, I will address the problem of averaging in general relativity. For this purpose, I will review the 3+1 decomposition formalism of the Einstein equation. As a simple example, I consider Buchert's approach, using conformal decomposition, I show how the averaging method adds feedback terms to the dynamical equations. I will also discuss its various generalizations and cosmol ... |
