Higher-spin gravity and torsion on quantized space-time in matrix models
Abstract A geometric formalism is developed which allows to describe the non-linear regime of higher-spin gravity emerging on a cosmological quantum space-time in the IKKT matrix model. The vacuum solutions are Ricci-flat up to an effective vacuum energy- momentum tensor quadratic in the torsion, wh...
