Query: Uniqueness and stability with respect to parameters of solutions to a
  fluid-like driven system for active-passive pedestrian dynamics   We study a system of parabolic equations consisting of a double nonlinear
parabolic equations of Forchheimer type coupled with a semilinear parabolic
equations. The system describes a fluid-like driven system for active-passive
pedestrian dynamics. The structure of the nonlinearity of the coupling allows
us to prove the uniqueness of solutions. We provide also stability estimates of
solutions with respect to selected parameters.
