Towards the framework of averaging in General Relativity


Date and time

Tuesday, 11th of July 2023 (20th of Tir, 1402), 2:00 pm (Tehran zone)



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 ...
