On the dynamical emergence of $S{U}_q(2)$ from the regularization of $2+1D$ gravity with cosmological constant

Niels Gresnigt, Antonino Marciano, Emanuele Zappala

The quantization of the reduced phase-space of the Einstein-Hilbert action for gravity in $2+1D$ has been shown to bring about the emergence, at the quantum level, of a topological…
