BKL conjecture. Within GR, for a generic inhomogeneous cosmology, the approach into the past to a spacelike singularity is vacuum dominated, local and oscillatory, obeying BKL or m…

In $3+1$-dimensional spacetimes, the BKL picture is the asymptotic scenario in which the singularity is spacelike and oscillatory, with asymptotic silence, matter becoming asymptot…

Let $I$ be the Mixmaster integral … For initial conditions $N_j(0)$ and $\Sigma_{\pm}(0)$ in the respective Bianchi class, BKL/Mixmaster conjecture. The integral is finite,…
