Higher order symmetry operators for Schroedinger equation Anatoly Nikitin
(Nikitin@imath.kiev.uau)
Abstracts It is well
known that the superintegrability of some classes of Schroedinger equations
is closely connected with the related commuting sets of symmetry operators.
We present results of our search for such symmetry operators and also
the completed group classification of non-linear Schroedinger equation
