The Tresse theorem and differential invariants connected with nonlinear Schroedinger equation

Abstract:
   The Tresse theorem and method of construction of all invariants and the differential invariants for a given Lie group is presented. Using this method, invariants for the nonlinear Schroedinger equation and its properties are investigated.
