Discretisation conjecture. Discretisation of the transformation $Y_\phi$ in these variables is feasible and therefore allows determining a discretisation of the charge $P_\phi$, wh…

Weak BKL conjecture. As the singularity is approached, the equations of motion can be well approximated by those of the truncated theory in the vicinity of the singularity. This is…

Let ${}^4M$ be a four-manifold foliated by spatial leaves $M_t$, with basic variables $(C_i{}^j,P_i{}^j)$, lapse $N$, and shift $N^i$. Let $D_i$ denote the spatial derivative opera…
