Covariant cosmological quantum space-time, higher-spin and gravity in the IKKT matrix model
Abstract We discuss a (3+1)-dimensional covariant quantum space-time describing a FLRW cosmology with Big Bounce, obtained by a projection of the fuzzy hyperboloid H n 4 . This provides a background solution of the IKKT matrix model with mass term. We characterize the bosonic fluctuation spectrum, w...
