We consider uncharged fluids without any boost symmetry STRESS-FX STRESS FORMULA on an arbitrary curved background and classify all allowed transport coefficients up to first order in derivatives.We assume rota- tional symmetry and we use the entropy current formalism.The curved background geometry in the absence of boost symmetry is called absolute or Aristotelian spacetime.

We present a closed-form expression for the energy-momentum tensor in Landau frame which splits into three parts: a dissipative (10), a hydrostatic non-dissipative (2) and a non-hydrostatic non- dissipative part (4), PRO L-THREONATE 144MG where in parenthesis we have indicated the number of allowed transport coefficients.The non-hydrostatic non-dissipative transport coefficients can be thought of as the generalization of coefficients that would vanish if we were to restrict to linearized perturba- tions and impose the Onsager relations.For the two hydrostatic and the four non-hydrostatic non-dissipative transport coefficients we present a Lagrangian description.

Finally when we impose scale invariance, thus restricting to Lifshitz fluids, we find 7 dissipative, 1 hydrostatic and 2 non-hydrostatic non-dissipative transport coefficients.
