Abstract:
The IKKT matrix model is viewed as a gauge theory of space-time and matter, which arises through an analog of the Higgs effect
on suitable vacua, describing 3+1-dimensional space-time branes in the weak coupling regime. In particular, we consider vacua
where the SO(9,1) invariance is spontaneously broken to SO(3,1). These vacua describe a cosmological FLRW space-time, on which
(an extended version of) gravity arises through quantum effects. Some progress towards understanding the resulting physics is discussed.
