Query: To the Gel'fand-Tsetlin realization of irreducible representations of
  classical semisimple algebras   It is shown that the Gel'fand-Tsetlin realization of irreducible
representations of the $A_n$ algebra is directly connected with a linear
exactly integrable system in the n-dimensional space. General solution for this
system is explicitly given.
