Abstract

In this talk I will explain how gravity can be extracted from the IKKT matrix model. 
IKKT is a non-perturbatively defined model of quantum gravity, which studies quantum dynamics of quantized (fuzzy) spacetimes, represented as matrix configurations.
I will explain how the weakly coupled regime of a 4d spacetime with fuzzy extra dimensions contains Einstein-Hilbert gravity at one-loop. 
Furthermore, for a class of solutions of IKKT, Covariant Cosmological Quantum Spacetimes, we study different mechanisms for dynamical stabilization of the extra dimensions.
