Open/closed string duality and relativistic fluids

Understand

We propose an open/closed string duality in general backgrounds extending previous ideas about open string completeness by Ashoke Sen.

• Our proposal sets up a general version of holography that works in gravity as a tomographic principle.
• We argue, in particular, that previous expectations of a supergravity/Dirac-Born-Infeld (DBI) correspondence are naturally embedded in this conjecture and can be tested in a well-defined manner.
• As an example, we consider the correspondence between open string field theories on extremal D-brane setups in flat space in the large-N, large 't Hooft limit, and asymptotically flat solutions in ten-dimensional type II supergravity.
