Nonlinear realization of superconformal symmetry and Liouville equation   superextensions
  It is shown that the method of nonlinear realization of local supersymmetry being applied to the n=(1,1) superconformal symmetry allows one reduce the new version of the super-Liouville equation to the ordinary one owing to the relaxation of the auxiliary equation of motion fixing the gauge parameters.
