Description
We derive the all-order effective action for a dissipative neutral relativistic fluid using a holographic Schwinger-Keldysh closed-time-path formalism, where the dual gravitational theory is Einstein gravity in an asymptotically AdS spacetime. The effective action is obtained by solving the double Dirichlet problem for linearized gravitational perturbations on a complexified asymptotically AdS geometry within the saddle-point approximation. The resulting boundary effective action, computed to quadratic order in AdS boundary data and to all orders in the derivative expansion, simultaneously captures both fluctuation and dissipation within a single covariant framework.
