Asymptotic Velocity Domination in quantized polarized Gowdy Cosmologies
Max Niedermaier, Mahdi Sedighi Jafari
Asymptotic velocity domination (AVD) posits that when back-propagated to the Big Bang generic cosmological spacetimes solve a drastically simplified version of the Einstein field e…

Dirac Observables for Gowdy Cosmologies regular at the Big Bang
Max Niedermaier, Mahdi Sedighi Jafari
Gowdy cosmologies are exact, spatially inhomogeneous solutions of the vacuum Einstein equations which describe nonlinear gravitational waves coalescing at the Big Bang singularity.…
