A Wilsonian effective action for (1+3+6)-dimensional emergent universes in the IKKT model

The IKKT model is a promising candidate for a non-perturbative description of Type IIB superstring theory.  A modified version of this model, with a Lorentz invariant mass term, is known to have many interesting emergent universe solutions.  This mass term, however, is often introduced by hand or serves as a regulator in the theory.  In this talk, I will show that the Lorentz invariant mass term can arise naturally in the IKKT model under certain choices of compactification.  When 6 dimensions are compactified, the S(1,9) symmetry of the Lorentzian IKKT model is naturally broken to SO(1,3) x SO(6), and the IKKT model admits (1+3+6)-dimensional emergent universes solutions.
