Nonexistence of smooth solutions for the general compressible Ericksen   -- Leslie equations in three dimensions
  We prove that the smooth solutions to the Cauchy problem for the compressible general three-dimensional Ericksen--Leslie system modeling nematic liquid crystal flow with conserved mass, linear momentum, and dissipating total energy, generally lose classical smoothness within a finite time.
