Accretion, mergers, and metastability of fuzzy spheres in a three-matrix model
M. Hrmo, S. Kováčik, K. Magdolenová +5
A three-matrix model that contains a plethora of fuzzy sphere solutions was defined twenty years ago. It has been shown that in a certain regime of the model, combinations of fuzzy…
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…
Minimal covariant quantum space-time
Alessandro Manta, Harold C. Steinacker
We discuss minimal covariant quantum space-time , which is defined through the minimal doubleton representation of . An elementary definition…
-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…
