Description
We focus on the question of how relativistic fluid dynamics should be
thought of as a Wilsonian effective field theory emerging from
Schwinger-Keldysh path integrals. Taking the basic principles of
Schwinger-Keldysh formalism seriously, we are led to a series of
remarkable statements and a broad programme relating relativistic
fluid dynamics and topological sigma models. Apart from the intrinsic
interest for this programme from the non-equilibrium field theory
viewpoint, we also emphasise its relevance to various fundamental
questions in black hole physics.
