Matrix Model Cosmology in Two Space-time Dimensions

arXiv:1409.7833 · doi:10.1103/PhysRevD.90.124056

Abstract

We examine solutions to the classical IKKT matrix model equations in three space-time dimensions. Closed, open and static two-dimensional universes naturally emerge from such models in the commutative limit. We show that tachyonic modes are a generic feature of these cosmological solutions.
