Spherically symmetric solutions of higher-spin gravity in the IKKT matrix model
Yuhma Asano, Harold C. Steinacker
We present a systematic study of spherically symmetric vacuum solutions of the IKKT matrix model, within the framework of semi-classical covariant quantum geometries. All asymptoti…

Gravity as a Quantum Effect on Quantum Space-Time
Harold C. Steinacker
The 3+1-dimensional Einstein-Hilbert action is obtained from the 1-loop effective action on noncommutative branes in the IIB or IKKT matrix model. The presence of compact fuzzy ext…

Exploring the gravity sector of emergent higher-spin gravity: effective action and a solution
Stefan Fredenhagen, Harold C. Steinacker
We elaborate the description of the semi-classical gravity sector of Yang-Mills matrix models on a covariant quantum FLRW background. The basic geometric structure is a frame, whic…
