Query: Quantum fluids in the Kaehler parametrization   In this paper we address the problem of the quantization of the perfect
relativistic fluids formulated in terms of the K\"{a}hler parametrization. This
fluid model describes a large set of interesting systems such as the power law
energy density fluids, Chaplygin gas, etc. In order to maintain the generality
of the model, we apply the BRST method in the reduced phase space in which the
fluid degrees of freedom are just the fluid potentials and the fluid current is
classically resolved in terms of them. We determine the physical states in this
setting, the time evolution and the path integral formulation.
