Dynamical Covariant Quantum Spacetime with Fuzzy Extra Dimensions in the IKKT model
Alessandro Manta, Harold C. Steinacker
We consider general FLRW covariant quantum spacetimes with fuzzy extra dimensions as classical solutions of the IKKT mat…

-extended gravity from the IKKT matrix model
Alessandro Manta, Harold C. Steinacker, Tung Tran
We elaborate further on the one-loop effective action of the IKKT model on 3 + 1 dimensional covariant quantum spacetime in the presence of fuzzy extra dimensions. In particular, w…
