| Abstract: | We construct a proper canonical transformation that reduces the quadratic Bose operator to a direct sum of finite-dimensional
quadratic operators each of which can be reduced by a finite-dimensional canonical transformation to one of the standard forms
corresponding to the standard forms of real quadratic Hamiltonians.
