Consistent holographic description of boost-invariant plasma

Understand

Prior attempts to construct the gravity dual of boost-invariant flow of N=4 supersymmetric Yang-Mills gauge theory plasma suffered from apparent curvature singularities in the late time expansion.

• This Letter shows how these problems can be resolved by a different choice of expansion parameter.
• The calculations presented correctly reproduce the plasma energy-momentum tensor within the framework of second order viscous hydrodynamics.
