The existence of non-trivial polynomial differential Hamilton operators for a multidimensional quantum system is considered an. Estimations of the number of independent differential operators, which commute with the Hamilton operator, is performed on the base of reduction to geodetic equations. This number does not exceed the Birkhoff number (homogeneous polynomials of momenta), which in turn depends on topological characteristics of the manifold.
