Application of the Galerkin method to the problem of stellar stability,   gravitational collapse and black hole formation
  Approximate approach based on the Galerkin method is suggested for the investigation of equilibrium stellar models, a relativistic collapse problem and black hole formation. Some results of its simplified version - energetic method- are reviewed, and equations for general Gelerkin method are presented.
