Singularities and gauge-gravity duality

Research output: Contribution to journalArticlepeer-review


We describe toy models of cosmology in asymptotically AdS space-times which have natural gauge theory duals. For spacetimes containing null singularities we argue that the gauge theory provides a well defined evolution in light front time even though the gravity description does not. For models with spacelike singularities examined so far, we identify the signature of such singularities in the gauge theory. However, it is not clear whether these singularities can be "resolved".
