# The late to early time behaviour of an expanding plasma: hydrodynamisation from exponential asymptotics

@inproceedings{Aniceto2022TheLT, title={The late to early time behaviour of an expanding plasma: hydrodynamisation from exponential asymptotics}, author={In{\^e}s Aniceto and Daniel Hasenbichler and Adri B. Olde Daalhuis}, year={2022} }

We use exponential asymptotics to match the late time temperature evolution of an expanding confor-mally invariant ﬂuid to its early time behaviour. We show that the rich divergent transseries asymptotics at late times can be used to interpolate between the two regimes with exponential accuracy using the well-established methods of hyperasymptotics, Borel resummation and transasymptotics. This approach is generic and can be applied to any interpolation problem involving a local asymptotic…
