Query: Integrable Supersymmetric Fluid Mechanics from Superstrings   Following the construction of a model for the planar supersymmetric Chaplygin
gas, supersymmetric fluid mechanics in (1+1)-dimensions is obtained from the
light-cone parametrized Nambu-Goto superstring in (2+1)-dimensions. The lineal
model is completely integrable and can be formulated neatly using Riemann
coordinates. Infinite towers of conserved charges and supercharges are
exhibited. They form irreducible representations of a dynamical (hidden)
SO(2,1) symmetry group.
