    "abstract": "An ideal compressible fluid is considered, with an equilibrium density being\na given function of coordinates due to presence of some static external forces.\nThe slow flows in such system, which do not disturb the density, are\ninvestigated with the help of the Hamiltonian formalism. The equations of\nmotion of the system are derived for an arbitrary given topology of the\nvorticity field. The general form of the Lagrangian for frozen-in vortex lines\nis established. The local induction approximation for motion of slender vortex\nfilaments in several inhomogeneous physical models is studied.",
