Holography and Cosmological Singularities

TL;DR

This paper explores how holographic dualities like Matrix Theory and AdS/CFT relate to null singularities in supergravity, showing that dual descriptions can remain well-defined even where supergravity becomes singular.

Contribution

It advances understanding of holographic duals for null singularities, demonstrating their well-defined nature despite supergravity singularities.

Findings

Holographic duals can be well-defined at supergravity singularities

Progress in understanding holography in singular spacetime regions

Insights into Matrix Theory and AdS/CFT in singular contexts

Abstract

Certain null singularities in ten dimensional supergravity have natural holographic duals in terms of Matrix Theory and generalizations of the AdS/CFT correspondence. In many situations the holographic duals appear to be well defined in regions where the supergravity develops singularities. We describe some recent progress in this area.
